Discrepancy #1.
In the FAQ Best Buy is listed, but when you click on the Retailer List it is not there. It also isn't in the drop down to start the process. Probably not worth it anyways.
Also, OT, but for those of you who are talking about losing small amounts on gift cards, check your state laws. For instance, in CA, if your gift card has less than $10 in value on it, the retailer is required by law to provide the balance back in cash if you ask. Some places, like Home Depot, just give it back to you automatically when the balance drops below $10 (at least at the self checkout lines)
