~7% @ Coinstar
They have a promotion recently that will give you 100% if you exchange it for gift cards.
Whatever you do don't bring it to a strip bar.
For some reason strippers don't like getting hit in the head with quarters and when coins get stuck in certain areas the night tends to end badly.
Not to mention dumping a handful of pennies in a G-string is a pain in the ass.
Is amazon the only gift card offered?
Darn it, you're a couple of days too late. Coinstar was giving an extra $10 GC if you converted $40 to a GC. Promotion ended 12/6/09.
