Why did I get two random usps money orders for $925 each?

They came in a big envelope from a lady in Philly. I researched the lady and she is like the head person of Urban Outfitters. I thought maybe I won a sweepstakes because I always enter a sweepstakes but there was nothing but the money orders in there. No letter, no nothing! Only thing I have is the return address. The money order was real. I deposited it in my account but this is so random! What is it?
