A few DP's for the $200 Staples MC.
1. At WM CS, only the first $99 worked. All the following $99 failed. Yes, I did the magic change payment.
2. Full amount did not work at the regular register. Tried twice. About half year ago, I was able to load $480 off a $500 BHN MC card.
3. SCO partial payment of $200 failed. Auto drain obviously failed. Both did not give a chance to change payment or ask for a PIN. So it was running as credit.
4. At Safeway chain, a $399 MO failed at the first swipe. So it was either not working or no auto drain.
5. At another grocery chain, only first swipe of $200 was successful.
