The way eBay was originally set up, the friggin' seller is supposed to leave feedback after payment is received, the buyer after the item is in hand and is pleased with the purchase. Unfortunately, there are only like five sellers out there that follow this. Mostly, they withold their feedback until the seller has left theirs so they can reciprocate. If the buyer leaves a negative because the seller lied about the item or the thing just plain doesn't look/work like it was suppsed to, then the seller will leave a negative out of spite, even if the buyer does everything correctly. It's just one more bit of dicketry involved with most of the jerkoffs on eBay anymore.

I usually don't leave feedback unless I get it first, like I'm supposed to. I'm at 90-something now (I've been registered since '03), and as far as I can tell, besides a pretty little star, there's no reward for having a feedback number higher than 10 (unless you're selling, which I rarely do). I've never seen a seller that refuses bids for people with less than 100, anyway. So yeah. The seller doesn't follow the rules, they don't get feedback from me. They're the ones who suffer in that arrangement, so they can eat it.
