I know it's petty, but it still pisses me off. I've lost almost 50 feedbacks as a buyer on Ebay. I'm the guy who pays usually within minutes when I win an auction, and never more than 24 hours. I leave positive feedback when the item is received, and of course the seller withholds his until he sees what I do (I don't do that as a seller, once the buyer pays me he's done his job and gets positive feedback).
But I keep getting screwed on receiving my feedback from sellers. I leave it, usually send a message through Ebay or an e-mail that I received the item, thanking them, and left feed back, and they can't take two seconds to return the favor. And it's worse with sellers that have more feedback. Makes no sense why it even bothers me, but I hate to do a transaction and not get the benefit of it from the seller. And it happens so often, like once every five or six transactions.
I know, what friggin difference does it even make, especially with the economy and other major problems happening right now, but it still bugs the crap out of me.........................

I think from now on, even as a buyer, I'm not giving any until I get some..............
