At Joanns, you can't use a coupon off on a coupon item - but, read the 20% or 25% off total purchase coupons carefully. Often they will say on all regular or sale price items. So, if item is 60% off on sale, you may also use your total purchase coupon. But especially this time of year, read the email coupons carefully. If an item says online sales only - it is online only. Normally a sale price is good in store or online - but this time of year that does not apply. This is the same with most retailers because of the holiday sales. Bottom line is to read the coupons carefully and save yourself a hassle.
