I am not sure, I do know that Walmart does have there on Mystery shopping. I just did one at Walmart but if was from a company called Certified where I had to go and do a audit. I like doing the audits or merchandising ones because you dont have to pose as a mystery shopper those interested please contact me at
oacia5804@yahoo.com I have done audits at Sears, Walmart, K-mart and Verizion wireless just to name some.
They are really neat it makes you feel in charge and when you walk in to a store for an audit those employees better have there stuff togather if not you write it up. It's like your the boss for that period of time.
