Buying rodents in small quantities will really add up if you have more than a few snakes. Petco and Petsmart would cost a ton verses what I paid through RodentPro(I always bought during sales with their coupon). Now I'm using BulkMice here in Houston and saving on doing which is really saving me money.

Like another said. Getting frozen rodents in strange positions is just part of it. If you don't like it straighten it out after it thaws. I promise you your snake could care less.
