Slickdeal forums members are complaining about a mass-closing of Amazon accounts. The reasons cited vary from having too high a percentage of returns, shipping to too many different addresses, and having too many different Amazon accounts. Guess they’re trying to tighten their bottom line and prevent loopholes from being exploited, but the net may have been cast too wide; some of the adversely affected users say the action was unfair and unwarranted. Couple this with the online retailer dropping the post price guarantee at basically the same time and you have to wonder if the boys in the Amazon backroom spent Labor Day Weekend earning their Six Sigma certificates.
