I went in to pick up some things to work on crafts for a Boy Scout Fundraiser.  I've always been told that Joanns/Michael's coupons are interchangeable and I have never had a problem in all the years I have been shopping there.  I had a 20% off of my entire purchase.  I didn't have much, in fact my total was only about $16.  I hadn't the cashier my coupon. She tried to scan it, but it didnt work.  I had to have her look at it and remind her it was from Joanns.  She then tells me I can't use it for my whole purchase, she will only take it off of the last item she rung up.  I asked her why because the coupon states the entire purchase and nothing I had was clearance.  She told me it was company policy and that she would call her manager.  The manager came and still said she would not honor the Joanns coupon after I had just watched her approve a refund for a customer in front of me that was clearly returning a used item with no receipt.  I had used this type of coupon at another Michaels before with no problem and no mention of this policy.  I informed her of this.  She told me I was more than welcome to go and try to make my purchase at another Michael's if they were willing to break company policy.  I do not believe she spoke properly to me as a customer.  Her customer service skills were definitely lacking.  I did not make that purchase and I went to Joanns down the street from this location.  This manager's treatment is definitely going to influence my decision to walk through the doors of that stood anytime soon.
