I don't usually shop Walgreens because I don't like their system- but here's a deal on diapers and wipes:
Buy Huggies Diapers or Pull-Ups @ $9.99 get $2 Register Rewards (use $1 or $2 coupon from newspaper insert or online)
buy in a separate transaction:
Huggies baby wipes @ $2.50 (use $0.50 off coupon from newspaper) use $2 Register reward to get them for free or nearly free after sales tax.
You can also turn these in to The Caregivers Marketplace for a rebate.
