Walgreens Diaper Deal this week

I am a big fan of Walgreens and their Monthly Register Reward deal on Huggies is much sweeter now becase not only are the diapers on Sale, but there is also the $3 off 1 coupon available now.
Here's the scenerio:
Buy 3 packs of Huggies Snug and Dry on sale for $9 each.  Total: $21
Use 3x $3 coupons from here
Receive $5 back in Register Rewards
Total Cost = $7 or $2.33 a pack plus tax!

Make this deal even better by submitting your reciept to Caregivers Marketplace for $.75 rebate per pack!
