I admit, this is kinda fun... Spending money on people for free
After having CSR from the beginning I was planning to cancel soon because of the high AF, and I live in the boonies and can't take advantage of most of these credits.
But then I realized I could buy stuff for my sister who lives in Dallas. I just got her 2 tickets to Guns n Roses (better seats, so cost $25), and $150 gift card for a restaurant (cost $0). I can never find good value on The Edit hotels where I travel, but I can get her a staycation without paying much.
It's pretty fun buying people things that don't cost you anything :-)
