I sent in two. I bought some for my daughter and I hated them (I watched them once and put them away--I don't think she ever even saw it). If I would have known I could return opened ones for a refund, I would have done it the day after I bought them. I figured I was stuck with the ones I'd opened and immediately returned the ones I hadn't yet opened. Being a packrat paid off this time (I hadn't gotten around to actually getting them out of the house yet).
I was more than happy to mail them back. Now I can use that money to buy more movies. Let's see... I recently bought Up. Monster's Inc, Tinkerbell and the Lost Treasure and Snow White all on blu ray on blu ray plus the three pack of Christmas movies (Mickey Mouse Clubhouse: Mickey Saves Santa, My Friends Tigger & Pooh Super Sleuth Christmas, & Little Einstein's Christmas Wish), Mickey's Magical Christmas: Snowed in at the House of Mouse on DVD, plus I already pre-ordered Santa Buddies on DVD. I think they'll get their money back from me fast enough.
