Newbie here. About to try a first MS run at Wally. Tried to understand what I'm doing from this thread and wiki, but still not 100% sure. Could you please tell me if I'm wrong?

I have three types of GC: Visa (Metabank), Visa (Sunrise), Mastercard (Metabank).
- I can't swipe more than 4 cards in a single transaction. [hard rule]
- Both VGCs have $99/swipe limit. Say the fee is $1. So I can have 99*4 - 1 = 395 MO per transaction.
- Metabank MC has no such limit. I can do more like 1K = 500+500 (-1 fee of course) or 2K = 500*4 (- fee of course.) Has to keep in mind that the payment type must be changed in advance.

Lastly... I can try both Visa and Mastercard GC at Kroger (as long as they sell MO). [Of course everything would be YMMV] Right?

Thanks!
