The trading card show floor app built for serious collectors and dealers. Virtual cases. Permanent QR codes. Asynchronous offers. Real deals without the crowd.
RUBUYIN replaces the chaos of in-person negotiation with a clean, digital offer flow — without losing the personal touch of a card show.
Create a digital Zion case for your cards. Each case gets a permanent QR code you print and attach to your physical box. Add cards, set asking prices, enable comps.
Buyers scan your QR code to browse your entire case on their phone — filtered by sport, grade, or rookie status. No more digging through binders.
Buyers submit offers on individual cards or bundles. Sellers counter, accept, or decline on their own time. Deals close with payment confirmation — no back-and-forth crowds.
Whether you're a weekend collector or a full-time dealer, RUBUYIN fits the way you work the floor.
A collector walks up to your booth and hands you their case QR. Your team scans it into the buy queue — the collector goes enjoy the show while you review at your own pace. When your offer is ready, they get notified and come back to close the deal.
You meet another collector on the floor. Both of you are logged in. Scan each other's cases via Quick Deal, select the cards you want, and build an offer right there. No awkward haggling — just clean digital negotiation.
Set up a dedicated buying station at your booth. Collectors scan in, your buyers review with market comps pulled from eBay and CardLadder, and offers go out with full approval controls based on spending limits. Scale your buying operation without scaling your headcount.
From weekend warriors to full-time dealers. No hidden fees, no transaction cuts. Just a flat monthly subscription.
RUBUYIN was born out of frustration with the way card show deals actually happen — shouting across tables, scribbled prices on napkins, and deals lost because the right person was in the wrong aisle at the wrong time.
RUBUYIN reimagines the show floor transaction from the ground up. Virtual cases with permanent QR codes mean your inventory is always browsable. Asynchronous offers mean deals happen on your schedule, not the crowd's.
We built this for the dealers working every show, the collectors hunting that one card, and the buyers reviewing stacks of submissions at a booth. This is the show floor app the hobby has needed for years.
