I have not printed this yet ( I am out of ink) but.. If there is not a size restriction on this it could work out free.
Walmart, Market Basket and other stores sell these individually for as low as $0.33 making them free with the $0.40 coupon.
If there is a size restriction then take the coupon to Shaw's where they will double the coupon to $0.80 and look in the reduced dairy section. Cheese sticks are a regular mark down and normally slashed to $1.50. With the coupon that would make them $0.70 for a pack.
