If you don't have a bank account or don't want the money to show, go to the WU office and pick up either a gift card or the Visa permanent reloadable debit card. Will save you lots of money over WU fees. Reloadable card goes for $9.95 and can be loaded up to $2500 at a time.
Warning!!! If any of you use a credit card to deposit there, your bank can charge a $10 cash advance fee. That's what happened to me with Washington Mutual.
