Eh, each has their trade-off. The transfer to PP costs coins here then a percentage to transfer to the bank plus $0.25. Transfer to Visa means you lose the change but it's like $1-2 over like the last 5-6 cards for me so far.
Only reason I'm doing it through Visa is because I'm broke. If I could wait 3 days I could save the 7500 coins for PP (and still lose $0.30 USD plus PP fees).
