TF from TF website are a bitch to return. You have to call and get a RA #. If you have breathed on it, you own it. For NM online, just return, they have a free return label. Yes, it takes like 7 days to get there. Just check off "changed mind" for reason for return. So far, knock on wood, they have taken back everything I have sent them. Also I did try to hasten the return by using the 5.95 if it fits it ships box. I was in normal state of being serious broke. Yes, it got back to Dallas in 2 days, but it still took 7 days for the money to get back into my account.
Barney's is a bitch to return to also. The actual website of Dior, YSL, Armani, Chanel I have never had issues with returns, even if used.
