Stackdeck scans live listings across thousands of eBay sellers, picks the lowest-priced copy of every card you need, and consolidates the cart so you minimize shipping. One decklist in, an optimized cart out — across the eBay seller network.
Most decklists touch 30+ different cards. To buy them at the cheapest combined price on eBay, you'd manually search each card, scan dozens of sellers, compare condition and shipping, and try to consolidate orders. Stackdeck does that for you.
MTG, Pokémon, Yu-Gi-Oh — paste the format you already use. We parse quantities and card names, then dispatch a search per card.
For each card, Stackdeck searches eBay's marketplace via the Browse API. We score every listing on price, seller feedback, condition, and shipping — surfacing the strongest candidates per card.
The optimizer picks the seller mix that gives you the lowest total cost, including consolidated shipping. You see exactly which eBay seller has each card and click through to complete purchase on eBay.
A real lookup for one card on the decklist. Stackdeck scores listings, shows you seller feedback and condition, and links directly to each eBay listing.
Live numbers from Stackdeck running today. Compare what you'd pay buying from a single eBay seller vs. Stackdeck's optimized eBay seller selection.
You buy directly from eBay sellers. Stackdeck doesn't custody inventory or act as a middleman — we surface the best eBay listings for your cards and link you directly to those listings to complete purchase on eBay.
Through the eBay Partner Network — eBay rewards us for sending high-intent buyers to their sellers. There's no markup on the prices you see. The price you see is the price the eBay seller is asking.
eBay has the deepest, most diverse seller network for trading-card singles — tens of thousands of individual sellers and dedicated TCG shops, with mature buyer protection, return policies, and dispute resolution baked in. For a single-card decklist, that depth means real competition on price.
Magic: the Gathering, Pokémon TCG, and Yu-Gi-Oh at launch. More games in consideration if there's demand.
Stackdeck defaults to "any tournament-legal printing" to find you the lowest price. You can lock to specific sets if you care about art, foil, or collector variants.
We participate in the eBay Partner Network — eBay's official program for tools that send buyers to their marketplace. Stackdeck is independently operated and not owned by eBay.
