Be sure to price check the Mentos gum at your Rite Aid. At my store they weren't tagged as being on sale but all 3 flavors rang up for $1.
M5 razor $4.99
14 Ritz sandwich crackers (6 pack) $.49 ea
12 Mentos gum $1 ea
$1 off 2 Ritz cracker coupons (x7)
$1 off 1 Mentos gum (x12)
$5 off $25 Rite Aid coupon
= total OOP $1.01 & will get back $4.99 in rebates for the razor.
