*Tomorrow only (August 12th), you may be able to get Huggies Little Movers Slip-ons at Babies R Us or Toys R Us for as low as $5.50 or even lower. They are on sale for $7, but if you have Huggies coupons, they would be even cheaper. Sheryl posted the details here.
*KC got a GREAT deal on wipes at Walgreens, and you don't even need Sunday coupons. To get the best deal, you would need both the Walgreens August coupon book (found in all Walgreens stores) and the Walgreens Infant Care Book (which I have found is hard to come by). Even if you only use the Walgreens August coupon book, it would make a Large pack of Huggies wipes for $3.99 or $3.49 if you have the July 17th Smart Source coupon insert. Check out KC's post here.
