I think they periodically go on sale. They've got a few different kinds of dog biscuits there, if that's what you mean by "bones". If not, you can always go to Gartnerd Meat Market. I know they have stuff for dogs. Wouldn't hurt to look there.
Check the Costco coupons for it.
As in biscuits, raw hide, or turkey jerky? Never seen actual BONES.
