I assume you are trying to use a coupon or surprise points. Diapers are usually considered health care, but if you are unsure, add the items to your card, and start the checkout page. At the spot where you can apply your points, it will have a note "includes $5.00 surprise points", then you know you are using them. If not, then nope, try again. I did that today, trying to figure out outdoor living items.
I hope I helped. Add me as your personal shopper, and I can help you with any future questions and orders. I can also send you a coupon for $10 off $50 home expires 7/22, with more coupons to come. Happy Shopping! syw.co/1wNZOR0
