I also buy the big bags and store it in an air tight container so the food won't go stale and so Corkscrew won't rip open the bag. His bowl can be full, but if there is a bag of food around he will rip it open and tear it apart. LOL but sometimes I can be so cheap last week I went into Petsmart with one of my coupons and saw a giant bag with a small rip and a sticker on it saying 10% off because of the rip. I ended up saving around $5 on just that one bag! Very exciting for a poor college student, I used the extra $5 to buy myself a burrito.
