I was able to load my temp card. I loaded a couple of $100 VGCs I had from Kroger for 4x fuel points.
I went to RA yesterday to load a $500 OVGC but it appears that they charge a $4.95 reload fee for all loads other than fee-free Serve cards based on the stock signage, so I didn't bother. I'll cash that out with a MO instead. 65c < $4.95.
