Comp = median of the last 5 completed sales for the same card and grade (shown under each card). Asking prices never count.
Max bid = the most you can pay and still make the target profit reselling at comp after eBay fee and postage. Aim = the strong-deal price (~35-40% profit).
Landed = bid + delivery to UK, plus ~20% import VAT/duty for non-UK sellers. Bids shown are what you type into eBay; delivery and VAT are already taken off.
Confidence = how many comps, how recent, how tightly they agree, and whether the title names the card number. Low = check by eye.
Where the edge is: auctions mostly finish near comp, so an auction "under max" today usually won't stay there. Buy-it-now listings already under max are the real finds: whoever clicks first wins.
Trend = last 5 sales vs the 5 before (only within 90 days). Rising cards get a slightly higher max.
