The big thing that flies in the face of this is that people spend tons of money on gas, grocery, and Wal-Mart cards. Some of those might be for underbanked people, but many aren't. With Amazon, for example, I'd guess most people just instantly apply the credit to their account and don't think about it after that. There's a thoughtfulness treat-yourself aspect to them, and there's a practical make-sure-this-can-be-used aspect. The data seemed to point that the practical aspect is missing, the gift cards are valued less in secondary markets than their more practical counterparts.
