You know something interesting happened. I was told I could use my 40% jax off on a sale item. She said it is now 82 dollars and I paid over the phone, when I got to the store, there was a wayyy different bag boxed and then I said- that is not the bag I ordered to come pick up, she then proceeded to say that they couldn't combine discounts. Call me crazy but I think that when manager realized of that transaction, since I wasn't there, they changed it on me and then fed me that story, I should of had that receipt emailed to me and not put in the bag, interesting I never got the original receipt either, since I said I didn't want that bag, coach SA kept it without me looking at.
Coach can do what they want to pricing, look at FOS or Coach Math, they can obliviously manipulate prices as they please. They can do transactions that they aren't supposed to do for example Friday I returned a FOS purchase to FP that was done via MC and CC, the SA overrides it and fully credits my CC. I agree, the Manager didn't want you to get the discount.
I hope you got your 40% off letter back.
