Buy 2 packs of Huggies Pure & Natural Diapers (usually $9.99 ea. on sale, to $11.99-$12.99 not on sale).  I'm not sure how much the diapers are right now, but even if they were $12.99 each = $25.98
- TWO of the new $2.50 off, coupons from HERE for Huggies Pure & Natural
- $5/$25 total RiteAid purchase from HERE (search for Rite Aid in the search box)
- $5/$25 total RiteAid purchase from HERE (it's a PDF)
- $5/$20 Video Values Reward coupon from watching 20 videos HERE!
- $1 off Huggies Video Values coupon from watching the Huggies video
Most RiteAids will let you use the $5/$20Video Values coupon AND one of the $5/$25 coupons, and some Rite Aids will let you use ALL 3 coupons, so...

=  ONLY $4.98 to $9.98 for BOTH packs!   
Then, submit for your $1 Single Check Rebate from RiteAid's digital system HERE!
That scenario was assuming they'd be $12.99 each - they are usually $11.99, but just playing it safe with the higher price.  If you need to, add something cheap to your cart to make your total at least $25 so you can use all the total purchase coupons.
