This also wipes out the opportunity to repeat DCBob's Delta Skymiles earning since Suntrust just switched all of their debit cards, including the Delta one, from Visa to Mastercard. Bummer.
Bummer no longer! Their MasterCard debit card policy has changed. I tested my Delta Skymiles Debit MasterCard on payusatax.com today using a hypothetical $10,000 Federal tax payment. The fee that was added to my payment was a flat $3.89! So I will definitely be using that debit card to pay my balance due for 2011.
