alerts for card people
Snipe deals
before anyone
else sees them.
Set an alert for any card, slab, or sealed product. CardboardSniper watches eBay around the clock, prices every new listing against real comps, and hits your inbox the minute something lists below market.
Custom alerts
Alerts built around your savings target.
Every alert has its own deal bar. Ask for 10% under market, 20%, or only the outright steals.
We price each new listing against real recorded sales, not asking prices, and only ping you when the savings clear your number:
▼ 21% below comps · $3,350 · move fast
≈ at comps · $14,900 · fairly priced
▲ 6% above comps · $1,300 · let it sit
Your rules, per alert
- Max price and BIN / auction filters
- Only capture listings ≥ N% below market
- Email on every match, only real deals, or never
- Find exact cards by PSA / BGS / CGC / SGC cert number
- Start from any eBay or TCGplayer link
