As far as kohl's goes. I represent one of their higher end mfgs and I have noticed that our MSRP is never what it is supposed to be. For example one of our products sells for $499.99 everywhere else but Kohl's will mark it up to $619.99 the put a $575.99 sale price on it.
We have price control on our products, they have a minimum price that it can be sold for but it does not set a maximum! So...Kohl's can use this tactic. My advice. Do research on the products that you intend to purchase, goto the mfgs web sites. Check the MSRP, Print it out & bring it to the store. Force them to honor the mfgs price.
I hope that this helps someone.
