About Sam's return policy: I called several Sam's in the Dallas/Fort Worth area, and they gave me different answers. Two of them said that there was no time limit as long as I had the receipt. One said 30 days, one said 60 days, one said 90 days, one said 6 months: all of these were stated after consulting with the store manager, and they were adamant about these policies even though their posted policy made no exceptions for TVs. One online rep said that it was 30 days even after I told her what the online policy stated (she even said that computers had a 15 day return policy after I told her it was 6 months). When I sent an email to online customer service, they called one of the Fort Worth stores, and they replied back that that particular manager stipulated a 90 day return policy with one year parts and labor (what the heck does THAT mean?). I replied with the question of whether or not I could count on their stated policy, but they never answered.
Obviously, there is much confusion as well as a lot of leeway with individual store managers. I don't relish the thought of driving from store to store with a big TV to return and having to battle with stubborn or clueless employees and managers.
At least call your local Sam's and find out what they say. Even then, the next rep could tell you something different. I suppose that as long as they have their return policy posted, you'd win the battle, but it's something to think about, and it's anxiety provoking.
