Someone recently found that if you searched for “medicine ball” on Sears.com, the first item listed was . . . a device you can use to stretch out a very different type of balls. And there was an EXPLICIT photo to go with the product. It was being sold by a third party company in Sears’s marketplace who clearly slipped past their censors and quality control . . . but once this listing started going viral yesterday, Sears pulled it down.
