Don't forget - you can shop too! They have a TON of stuff in their Winter Sale at a good price AND almost everything starts at giving 14 full bowls of food with the purchase of the item.
Heck, I'm debating whether the stuff I'm buying now is going to just be for me, or if I should start saving a stash for next year's Secret Santa.
ETA: I spent under $30 with shipping ($1 US shipping for orders over $20 right now!) and with my order gave 70 bowls of food!
That's shopping you can really feel good about!
