Price Check on Boxes of Huggies Diapers at Publix

When I was in Publix today I checked on the price of the diapers that were included for the $5.00/1 found in the ad. The shelf price was $21.99, which was lower than I expected for Publix. However, I also noticed that the number of diapers per box had gone down from 92 to 88. With a stacking scenario this will be a deal for disposable diapers.

Scenario:
Buy 1 box $21.99
Use $5.00/1 Publix Ad Coupon
Use $4/$20 or Better Competitor Coupon - Look for a new Walgreen's coupon to come out this weekend.
Use $1.00/1 (8/24 S) OR $1.50/1 (Home Mailer)
Final cost $11.49 = .13/diaper for size 4

Bonus $1.00 added to Upromise Account if e-coupon is loaded and card is swiped.
