Can I use these coupons on every item in store

No you can’t use the coupons on all items. I was unable to use a coupon on a more expensive item. So you need to read the fine print also you can’t use them on discounted products or with gift card purchases. But to be honest you should be able to use them on most items also you can use the coupons at buy buy baby stores which is owned by the same company. Some times you can’t use them on special offers either but apart from that I’ve never had a problem. Good luck just read the fine print on you coupon.
