To be honest, I don't usually check the return policy that closely. I have not returned anything, nor have I been unhappy with my purchases. If I got something defective or the wrong item/order, then I would expect the store to make the appropriate exchange for me and expect the store to pay the shipping.
On a side note, I'd like to bring up how I feel about backorders. I don't usually mind if something is backordered and I am given an approximate delivery date. If the item will not be available for several months, I would want to be contacted to see if I still want it. I had this issue with Hancocks of Paducah. An item showed up several months later without warning. I had read on other sites that the item I ordered was being discontinued. I never expected to get it. I think it's important to keep the communication open. :)
