DP:
successfully bought MO at Publix in S FL with MCGC (Pathward, BHN) bought from Staples.
$200 GC, bought a $199 MO. Paid the $.99 fee also from the GC, same transaction, so 1 cent left on the GC.
I had set a pin on the GC beforehand and had no trouble with it coming up as debit. Wish I brought the rest of my MCGCs on this trip to FL!
