Anyone know or have any experience with returns/refunds/exchnages of the Xbox 360 at Costco?

I currently have a dead unit I'm trying to get repaired by MS that I bought at WalMart 4 months ago with an extended warranty and it is turning into a headache.

Wondering if I might just buy a second unit from Costco at least for now and return it if it has issues or if I ever get my current system replaced.

Also any comments on the Walmart policy? I assume I can only return to them if within 90 days which has not passed. Is there any chance they would still do a return or am I stuck dealign with MS support at this point?

I bought my 360 at WM 2 months ago. I was told right when I purchased it that if I had any problems with it I had to call MS and that WM would not accept any faulty returns.

Costco will take return. No question about it. They will slap a "Non-resaleable" sticker on it and refund the whole thing.

Better hurry up though:
