Each Sniper deal is tied to a specific eBay listing. When that listing ends, we mark the deal expired. Causes:
- Listing ended — the auction ran out or the BIN sold
- Listing 404'd — the seller pulled it or eBay removed it
- Listing has 0 quantity — multi-quantity BINs we mark expired when stock = 0
Expired deals stay visible for 24 hours so you can see what was available, then drop off the All Deals tab. The Sold tab on the card detail page may show the final sale price if the listing actually sold.
