...who forget to leave feedback until there are a dozen completed auctions and we do them all at once. I NEVER look at who has left feedback for me before I post feedback, but I FREQUENTLY find that I've neglected to post feedback on completed transactions, both as a buyer and a seller.

Folks I deal with will get their positive feedback sooner or later, unless they really do something bad, but they may not get it the same day they complete their end of the transaction.
