The most common answer is no (it's in the fine print ALWAYS). But there are a couple of cashiers at a Joann's I know who will scan any coupon and are happy to scan more than one. Just check the coupon dates and be sure they're good when you're going. And of course you can always go up to the register with two or three things and if they wont do more than one coupon you can say you don't want it, leave come back in and buy it anyway. That doesn't work so well for cut fabrics though.
