Seriously, four defective SP3's in a row. Retailers have every right to eventually cut off customers. I'm not judging the OP but that doesn't mean I agree he's been wronged by Best Buy. Best Buy is here to make money for its shareholders.
Sorry but I have to giggle at this notion.
How exactly is Best Buy loosing money for its shareholders by a customer returning a faulty product? I'm pretty sure every large retailer in the US has an exchange / return policy.
Many retailers have a similar 2-week return policy that Best Buy has and several go above and beyond the 2-week. Sam's Club and Costco for instance have 90-day NO QUESTIONS ASKED returns..
I've returned items to Apple before (no ID asked for and no 3rd party tracking), I've retuned items to Sam's Club before (no ID asked for and no 3rd party tracking), , I've returned items to Walmart before, (no ID asked for and no 3rd party tracking), ect, ect, ect.. and these were pain and trouble free.
Best Buy goes out of their way to harass it's customers by requiring to show ID, then logging your information with a 3rd party to track you. I don't know of any other company that does this, and if I find out they do, then I'd avoid them just like I avoid Best Buy.
If Best Buy is worried about making $$$$ for the shareholders at the expense of treating customers with respect then they will fail and their won't be any shareholders left when the company goes out of business..
Best Buy had better be worried about keeping the customers they still have. I know a lot of people who don't go there any more. Customer service rules supreme in this day and age when with a click of a mouse you can beat Best Buy prices without even getting off the couch..
I typed way more than I wanted to in response to your post but it struck me as very, very odd..
