Science Diet Dog Treats - CHEAP (or possible moneymaker!)

Petsmart has these treats on sale 2 for $5.  Science Diet is offering a $3 coupon for these treats here.  Yes - you saw correctly $3 off a $2.50 treat! 

There's three possiblities that may occur:

1)  They will take 2 coupons for 2 treats and will apply the $1 overage towards the rest of your purchase.  I would suggest picking up something else small - like maybe a few cow hooves when you go to the register.  They will never hand you $1 out of the register when you make a purchase so you'll need something else.  If they won't apply the overage to the other items, you can always have them taken off the bill.

2)  They will change the value of the coupons to $2.50 to cover just the cost of the treats and the treats will still be free!

3)  They will only take 1 coupon for the 2 treats.  This is the possibility that shouldn't occur, but it wouldn't surprise me if someone tried to get away with it.  It would still make it only $2 for 2 bags of treats.
