There won't be any difference in price (if there is it will be a negligible amount) so I would base my decision on whether or not I am going to get a product replacement (PRP) or service plan (PRS). Personally I think the Best Buy has better plans than Walmart and they don't don't give you any crap when you return your product if its faulty. If you don't plan on getting a PRP or PRS, I would just buy from whatever store is closer.
