So let me get this straight,

You go buy a $10 kroger gift card from in store. Go out to the gas station and have them add $490, then $500, to get to the 1k limit.

Doing this nets you 1k in gas points (or 4k this weekend)? Or are you just using it as a way to get gas bonuses (like Ink 2x or Amex BCP 3% or PenFed 5x)? EDIT: Or both?

You then go in and buy two $500 Gebits and incur the $11.90 fee?

Then you can just go out and reload 2x$500 and repeat the process?
