I have a JoAnn's and Michaels in the same mall. Had a 50% off at JoAnn's but their crochet hooks were 15% off so i couldn't use it. Walked over to Michaels and used the JoAnn's coupon. So many times when I have a good JoAnn's coupon it seems everything I want is already on sale.

You may already have your answer by now but if not ...

I was told at Michael's (in JAX, FL) that their cash register is programmed to only go up to 50% off coupons. I took an AC Moore 60% off coupon in there & the most that they would give me was 50% off. It was a product that both stores carried.

Well, you all correct that I should call, which is what I did. Since both stores are an hour away, I didn't want to go and not be able to use the scratch off coupon. When I called, they put the manager on and she asked how much it was for and I told her it was 60% and she said yes they would honor it. I got the Crayola Light Up Tracing Pad with no problem at all, so I'm doing the happy dance. Thanks for all your help.

Our Joann's & Michael's take each others coupons.
But you can't use the Joann's fabric coupons at Michael's.
I know that it does not happen in all store.
You have to ask them first.
