One of the rebate programs I participate in is Caregivers Marketplace. It’s a rebate program for lots of different brands, see their eligible list. I only ever get rebates for Huggies, but they give me $1 back for each pack I buy. Not bad, considering I only ever pay for them with ECBs in the first place. Cottonelle is one of the participating brands too, and I’ve gotten free stuff at Walgreen’s then submitted the rebates. Nothing like getting paid to shop.
Website is here. Registration is free and it’s very easy to do. And like my other rebate checks, it’s a nice surprise to get in the mail.
