USPS Money Order Question

[sfmmrules!]

I sent a money order for an auction I won on Ebay but I changed my mind & didn't want the seller to send what I won. He returned the money order I made out to him. I saved my reciet. Will I have any problem cashing it to get my money back? I am worried because the money order is worth $76 & I need that money!
