Amex Sync deals are much better. Hardly any good deals. Works the same since you have to load the BofA offer just like with Amex prior to going to the store. You can take advantage of the offer once. It's not repeatable unless the offer comes back.

BofA deals will pay even if the whole order contains gift cards. It takes 1-2 months to go from pending to being paid. The vendors are almost always stores or restaurants that do not sell VGC, MGC, or AGC.
