Agree with above, you should have opted for Citi double cash, Amex fidelity, or even Cap One QS card if you were after cash back. These are just a few that give good overall return. There's others if you had specific goals in mind. TYP is more valuable as a travel currency at this point. Your best bet would be to just convert them for statement credit. No guarantee that getting a WalMart GC will let you buy a prepaid debit card or even VGC at Wal Mart. I asked an employee the other day and she said no you can not buy VGC with WMGC. So you may end up with a bunch of WM money esp if you don't spend there.
