Buying and selling gift cards in bulk is different, and bulk rate may be higher or lower than going rates on smaller amounts. Typically, bulk buyers do not deal with small quantities regardless of the rate (and even if they do, they often need much more).
$5k minimum is an arbitrary threshold that's been chosen for this thread, and some of the brands listed below are available on a much larger scale, in the millions. Welcome to post other bulk buy and sell offers here, too.
