Had to add a couple of more after my hands-on experiences at a card show on Saturday.
The one guy I had never bought anything from due to his unreasonable prices, told me he hasn't been 'allowed' (pandemic) to do any shows for two years (he was at every show I've ever attended since being out here). Looking at the 'low' price stickers in his case made me think there must be some terrible, unseen issues with the cards, but I asked to see them anyway. As I shuffled through the toploaders, some of the stickers actually fell off. That's how long they'd been affixed!! When I removed the cards for close inspection, they turned out to be in fine a*s shape, so I started buying like crazy. Seren-freakin'-dipity!!!

When a seller’s prices before the pandemic were stupidly high, but since he hasn’t done a show in a couple of years, the old price stickers on his toploaders remain unchanged and now make the cards look like sweet bargains in today’s market.

Buying a graded card at a show, because you thought the price was a steal, but when you got home and checked out the listings on eBay, you saw it could be readily had for half of what you paid.
