I have used many coupons when I go there but always assumed that I could only use 1 coupon per visit, however, after doing some research that might not be true.   It’s up to your manager or cashier.

As of 11/6/2011, I went to JoAnn and I confirmed with the cashier that you can use more than 1 coupon per visit, however, they don’t double.   I was able to use a 40% off coupon on 1 regular price item and a 25% off the whole store purchase on regular and sale priced items excluding the 40% off coupon item.  The register automatically detects the coupon used.   If you have a 2 coupons that are40% off a regular priced item YOU can use both coupons 1 on each item.

Here is a forum from 7/2009 talking about the coupon policy.  Click HERE to read it.

Here is the coupon policy via the FAQ for online orders on JoAnn.com:

We’re sorry, you can NOT use two coupons or promotion codes on one order.
