Thanks for the replies. I guess I'll wait to read the results come the 1st for both of these cards w/ respect to Serve loads and go from there with my strategy.

Now, if I could only easily figure out which, if any, of the office supply stores near me carry $500 VGC's. The more I'm reading, the less I'm counting on this being available. But since (5) $200 VGC's from an office supply store will net me more than (2) $500 VGC's from a grocery or drugstore, I'll still stick with it.
