I have found that they will take all of my coupons. But the 25% only comes off of the total that didn't get 40 or 50% off. Do that make sense? I bought a cutting matt that was on sale and then bought batting and used a coupon. I had a 20% off total purchase. My total savings off of final price was only 6.00 so it didn't take 20% off of the items that I used other coupons on. When I asked they said that it wouldn't apply to items that I used other coupons on.
