Money back at dollar general

This is an order I just placed at dollar general for pick up.
$1 off arm and hammer mobile coupon
$4 off razor refills mobile coupon (was more than the item itself so it was money back on the order)
$4 off skintimate razors mobile coupon
$1 off toothpaste mobile coupon
$5 off $25 mobile coupon.
Order total came to $15.59 for everything including a box of diapers!
