Just like the Gift Card Churning Page that I maintain of gift card churning advice and miscellaneous information, I have posted a page called Useful information for Manufactured Spend and Gift Card Churning.
The page contains places that I know of that offer cash back from debit cards as well stores that allow you to buy money orders and online vendors that place an authorization hold, in case you are trying to drain out a prepaid card and are not sure why a transaction cancels.
