Like a lot of others that can't or don't want to go to the trouble of breeding my own rats I also order online in bulk. I've never run into an issue with buying 6 months worth of food at at time for my 2 boas and always repackage them in better ziplock bags when I order from any of the suppliers that don't use the best sealing methods. Never ran into an issue with freezer burn or the snakes refusing because the rats have gone bad.
