Just a sugestion..
We have tried ALOT of different suppliers, and the BEST by far, has been cajunmice.com. The prices and shipping, is lower than the "other guys", BUT the quality has been first rate!
You can specify size, amount you want to buy of each, and you will get what you ordered!
PLUS Rhonda, (the owner), will help you if your not really sure about what size, or what your snake really needs! Case in point.. we just got a little variable king snake, we mentioned his size, (6 to 8 inches), Rhonda sent us 50 VERY small pinky mice that are PERFECT!
All her feeders are vaccum packed, shipped to your door overnight, and packed in dry ice. Also you will get a return reciept and a price list in the mail.
We have ordered ALL of our feeders from her for the past 1 and 1/2 years, and have always been very happy with RHONDA.
Just our .02 cents
