Question about the purchase

[ihazcarrot™]

This game is on sale, and yet a credit card i have money on isn't supported by steam, nor paypal. Is there a way to purchase this with Maestro regular credit card? I have a other Visa card that i can use and that i normaly use for internet purchases, but the thing is ,on weekends, they tend to hold-up all the cash transfers between banks. So is there another way?
