CardPeak Consulting25 mistakessports card sellers make on eBay — and exactly how to fix each one.
Drawn from real repeat-seller behaviour — listing copy buyers actually search, the photography stack that earns trust, packaging that survives a SNAD dispute, and the pricing rules that get you a higher final sale. Each section is a two-minute read: the mistake, the fix, and the easiest place to start.
Tonight
Fix your titles in fifteen minutes.
Lead with "Year Brand Player #Team Card# Grader/Grade". Most buyers search that order — and skim in the same order.
This week
Re-shoot every photo.
Mat on dark grey, square-on, both sides. Re-listing the same card with corrected photos routinely lifts final sale 15-30%.
This month
Set a floor on Best Offer.
Without a floor you accept the second automated lowball. With one, you hold the line and still field the offers you want.
