More of a rant than anything else -
Some time ago I made an offer of $8 for an item listed at $10, and the seller declined outright - which, fine, you do you. I thought it was a bit rude not to counter-offer at least, but again - not my business. Being a bit put-out about it, I didn't buy anything from that shop.
Maybe 3 months later, that and a number of other items in my niche are still for sale in that shop, and I'm in a position to buy them. I try to add them to my cart but I get the 9999 "cart full" error. My cart is empty, and it doesn't happen for any other shop - she's blocked me apparently (???).
I'm absolutely the most prolific buyer in my very specific niche, and while I don't think they'll NEVER sell to someone who isn't me, it'll take a really long time to move all of them. I'm a collector and it's so irritating to me.
My rhetorical question to the forum: I get using Best Offer to weed out low-ballers, but seriously?! Blocked for 20%?! Maddening.
