On another webforum they posted that at PetSmart there is a sale on Science Diet food. There is a rebate for up to $9.00. Here is the link for a $5.00 off coupon but you cant use both at the same time. What I did was buy two bags and had the clerk ring them up seperately. That way I was able to use the coupon for one and use the rebate for the other. Science Diet Coupon
