If you buy them in a large bulk they are a lot cheaper. Without the bulk pack I got (200), I wouldn't have food for my snakes. 200 has lasted me about 2 months with 12 snakes. I still have about 100 left. Most of my snakes eat more than one pinky per feeding. Mama eats 3, it used to be 5 but she as getting fat, snakey eats 1, he's too small to eat any more... Snap and Ember are getting larger than Mama, almost, and eat 2 a week. And, my 5 babies and 2 (almost) yearling eat about 1.5 pinkies between each other, that are cut up.

To keep the snakes healthier, or just to supplement their diet, perhaps you could save 5-10 dollars a month to pay for a bulk pack and shipping. I know it's expensive, but health wise, I find its worth it.
