I purchased 50 small/medium rats from Layne Labs. The rats them self were $90.00, shipping was $33.08. I'm in Phoenix,AZ and I believe the company is based in California.
The rats came frozen and promised, packaged with dry ice. The gram size quoted from their website was 70-90 grams, I weighed 10 of them, all of them fell within this range.
Completely satisfied with my purchase will order from them again. Here is the companies website and a couple photos as well.
