If you order from Pet360 your first order gets 20% off, and if you order 5 50lb bags of native earth rodent block it comes out to $80 with free shipping (regularly $100 with free shipping) So that's less than $20 per bag for your first order, and $20 per bag after that.

You can also use pig food, but you HAVE TO check the nutrition information to make sure that it's close to rodent chow. I used I THINK Mazuri Sow and piglet feed? Something like that.

Keep in mind the pig food is cheaper (about $16 a bag) but it also gets wasted more than the blocks.

It's basically down to preference. I recently switched from pig food to Pet360 orders of lab block.
