This is not counting the MO fee if that's what you're doing with the GCs, but that's the same either way. Of course if you don't have any gas stations that sell GCs with CC, the comparison doesn't matter.

I sometimes buy the $200 GCs when there's a sale, and it is a much faster way to gain UR points, but under normal circumstances I stick to gas stations for my UR needs.
