I have this card from back in 2010 when i first learned about rewards CCs, but didn't understand the true value of rewards. I don't want to close it since it is one of my older CCs. What in the heck can I do with this card to make it useful? I've thought about buying GCs with it, but I'm not sure if that is viable since I can't see if they count for poitns in the T&Cs.
