Cards sell in more places than almost any other product. Knowing the full mix — and what each one costs you — is half the battle.
Quick answer. Cards sell across live-streaming auctions (Whatnot, eBay Live, TikTok Shop), your own website (usually Shopify plus a card platform), marketplaces (eBay, Amazon, TCGplayer, Cardmarket), a high-street shop, and trade shows. The most successful businesses use a deliberate mix, not just one.
One of the reasons the trading card market is booming is the sheer number of ways to sell. A modern card business rarely lives on a single channel — it runs a deliberate mix, each channel doing a different job. Some drive volume and audience, some protect margin, some bring reach, and some build the community that keeps buyers coming back. This guide walks through the full landscape, how each channel actually works, and how to decide where to put your energy.

Live-streaming auctions
Live-selling is the fastest-growing channel in the hobby, and for many card businesses it’s now the main event. The format is simple and addictive: you go live, rip packs, auction singles and run giveaways in real time, while viewers bid and buy in the moment. It works because it combines three things — entertainment, scarcity and community — all pushing towards impulse purchases.
The main platforms
Whatnot is the best-known and the platform most associated with cards, built entirely around live shows. It isn’t the only option: eBay has its own live-selling format, and TikTok Shop’s live features put selling right where a huge audience already spends its time. Other platforms continue to launch live formats as the category grows.
How the model works
You schedule and run a show, sell through live auctions or buy-it-now, and the platform handles payment and takes its cut — typically a category-based commission plus payment processing — before paying you a net settlement. You then ship. It’s high-volume and impulse-driven, which is brilliant for moving singles and sealed rips quickly.
The trade-offs: you’re selling on someone else’s platform and paying their fees, margins can be thinner than on your own website, and it’s genuinely time-intensive because you’re effectively performing. But the audience-building is baked in — every show grows your following.
Show formats that work
Within a live show you have several formats to mix. Straight auctions build excitement and can push individual cards above market when the room is hot; buy-it-now listings give buyers certainty and move known stock quickly; and giveaways and “sweeps” keep viewers watching and reward loyalty. The two that confuse newcomers are breaks and rips: a “rip” is simply you opening sealed product live and selling the singles or the thrill of the reveal, while a “break” is where multiple buyers each pay for a share — a team, a set of slots, or specific cards — of a box or case you then open, with the hits distributed accordingly. Both turn the act of opening product into the product itself.
What you need to get started
The barrier to entry is low. You need a phone with a decent camera, a consistent schedule so viewers know when to show up, your stock organised and to hand, and a smooth packing-and-shipping routine for afterwards. The platform handles payment and much of the logistics; your job is to be reliable, be entertaining, and ship quickly. Consistency matters more than production values — a regular seller with a modest setup will out-earn a slick one who shows up sporadically.
Your own website
A branded online store is where you keep the most margin and the most control. You own the customer relationship, the data and the brand, with no marketplace taking a cut of every sale.
The platforms card businesses use
Most card stores build on Shopify, usually with a card-specific layer on top — BinderPOS, TCG Sync or Storepass — which adds a storefront, buylist, deckbuilder, pre-loaded card catalogues and syncing to marketplaces. WooCommerce (on WordPress) is a common alternative, and larger operations sometimes run on Magento/Adobe Commerce. The card-specific layer usually matters more than the underlying cart, because generic e-commerce struggles with card-level catalogues, conditions and live pricing.
The trade-off is straightforward: a website gives you the best margins and full ownership, but you have to drive your own traffic through SEO, content and marketing rather than plugging into a ready-made audience.
Marketplaces
Marketplaces hand you a ready-made audience in exchange for fees. For most UK card businesses, eBay is the workhorse, and Amazon carries sealed product well. Alongside the generalists sit the specialist card marketplaces: TCGplayer, which is huge in the US; Cardmarket, the major European platform; and others such as Cardtrader and Mana Pool.
A good inventory system will sync your stock to several of these from a single pool, so you list once and sell everywhere. The trade-off is fees and price competition — marketplaces bring high-intent buyers but put pressure on margin and give you less ownership of the customer.
The high-street shop and events
A physical store adds walk-in sales of singles and sealed product — and, just as importantly, events. Friday Night Magic, pre-releases, leagues and tournaments turn a shop into a community hub, and community is what drives repeat spend and loyalty.
The events model layers several income streams: entry or ticket fees, stock sales around the event, and buylist trade-ins where customers sell cards back to you for cash or store credit (a valuable sourcing channel in its own right). The trade-offs are the obvious ones of premises and staff costs, and dependence on footfall — but the community and local brand a shop builds are hard to replicate online.
Trade shows and conventions
Conventions and trade shows are a distinct sales model worth understanding, because the economics behave differently from day-to-day trading. Revenue tends to come from several formats at once:
- Straight stock sales: singles and sealed product sold from the booth.
- Mystery boxes: fixed-price mixes of product, sold on the appeal of the unknown.
- Breaks and rips: buyers pay for a slot in opening a box or case, with the hits distributed among participants — a hugely popular live format that also works on stream.
- Competitions, raffles and tournaments: which draw a crowd and drive footfall to the booth.
Because a show is a burst of concentrated sales against real costs — stand fees, travel, accommodation — its margins and cash flow don’t look like your normal trading. It’s well worth tracking events separately so you know whether they genuinely pay.
Choosing your channel mix
There’s rarely a single “best” channel — the winning approach is a deliberate mix, matched to what each does well. Live-selling drives volume and audience; a website protects margin; marketplaces bring reach; a shop and events build community; and shows deliver high-energy bursts. Each has a different cost and a different margin, so the mix should be chosen on purpose, not by accident.
The only reliable way to know which channels actually make you money is to measure them. Using Xero’s tracking categories for divisional reporting, you can see profit by channel — and the results often surprise people. A busy stream can turn out to be more turnover than profit, while sealed product quietly sold on eBay might be your best margin. Let the numbers, not the buzz, guide where you lean in.
How the channels feed one system
However many channels you run, they should all draw on one inventory source of truth that pushes stock out to each channel and syncs back the moment something sells, so you never double-sell the same card. On the money side, each channel’s sales and fees flow into your accounting system, ideally as clean summaries, with tracking categories keeping the channels apart for reporting.
| Channel | How it works | Fees / margin | Best for |
| Live auctions (Whatnot, eBay Live, TikTok Shop) | Live shows with real-time bidding and buy-it-now; platform handles payment. | Category commission + processing; margin often thinner. | Volume, audience-building, sealed rips. |
| Own website (Shopify + card platform) | Branded store, usually with a card-specific storefront and buylist. | Best margin; you fund your own traffic. | Margin, brand and customer ownership. |
| Marketplaces (eBay, Amazon, TCGplayer, Cardmarket) | List into a ready-made audience; sync from one stock pool. | Fees + price competition; high intent. | Reach and buyer trust. |
| High-street shop & events | Walk-in sales plus tournaments, leagues and buylist trade-ins. | Premises and staff costs; strong loyalty. | Community and local brand. |
| Trade shows & conventions | Booth sales, mystery boxes, breaks/rips and competitions. | Stand and travel costs; concentrated bursts. | High-energy sales and exposure. |
Which channel should a new business start with?
If you’re starting out, resist the urge to be everywhere at once. Begin where the audience already is and the setup cost is lowest — for many card sellers that’s live-selling on an established platform, or listing on eBay, both of which put you in front of buyers immediately without building anything. Prove you can source, price and ship profitably there first.
As you grow, add your own website to protect margin on the stock you can sell direct, then layer in marketplaces for reach and, if it fits your model, a shop or a presence at shows for community and sourcing. The principle is to add channels deliberately, one at a time, only once the last one is running smoothly — and to connect each to the same inventory and books as you go, so complexity never outruns your systems.
Frequently asked questions
Do I need my own website if I already sell on Whatnot and eBay?
Not to start — many businesses run happily on live-selling and marketplaces alone. But a website is worth adding as you grow, because it’s the one channel where you own the customer and keep the most margin, with no platform taking a cut of every sale.
What’s the difference between a break and a rip?
A rip is you opening sealed product yourself and selling the singles or the live reveal. A break is where several buyers each pay for a share of a box or case — by team, slot or specific cards — which you then open, distributing the hits to whoever bought them.
Can I sell the same stock across several channels at once?
Yes, and you should — but only with an inventory system that syncs in real time, so a card sold on one channel is removed everywhere else. Selling the same single twice because two channels weren’t in sync is a fast way to upset buyers.
Which channel has the best margins?
Usually your own website, because there’s no marketplace commission and you set the prices. Marketplaces and live platforms charge a fee for the reach and audience they provide. The right answer for your business is whichever combination nets the most after all costs — which is why measuring channel profitability matters.
Do I need a card-specific platform, or will Shopify on its own do?
Shopify alone struggles with card-level catalogues, conditions and live pricing. Most serious card stores run a card-specific layer (BinderPOS, TCG Sync, Storepass) on top of Shopify to handle inventory, buylists and marketplace syncing. The accounting-software guide covers how this fits together.
