Savings this weekend

Walgreen's has another $5 off $20 purchase coupon this weekend. (I wish I hadn't gone earlier this week!) Here's my scenario for this coupon:

Oral B toothbrush $4.49
Loreal Cleanser $7.99
2 packs Huggies diapers (size 3) $9.99 each
1 pack Huggies wipes $5.99

subtotal $38.45

minus the following coupons:
$0.75 off Oral B toothbrush (09/28 p&g)
$1 off Loreal Cleanser (I think there was one a week or two ago)
$1 off Huggies diapers x 2 (09/28 ss)
$1 off Huggies wipes (got in the mail)
$5 off $20

total $28.70
receive $7.99 in rebates
receive $9.50 in RR's
total oop: $11.21 (If I were to pay that much for only the 80 diapers, it would work out to 14 cents per diaper!)
