I've used a pre-paid Mastercard issued through RiteAid pharmacies in the regions that have RiteAid and through other stores whose names I don't recognize in other parts of the country. The fee is $9.95 for the initial load of the card (minimum $20, maximum $500 - you can "upgrade" to $2500 for an extra fee)...each subsequent load on the card is a $4.95 fee. There is a $4.95 monthly maintenance fee but if you drain the card of funds before that date, the issuer just eats the fee. The info website is mymccard.com.
