Been buying at conventions/petstores, just got my 1st online order from Layne Labs. Shipping was hefty, however all my babies are growing and are at weird feeding sizes. They came out on top as far as size selection (having in between S-M rats lol) and let you buy smaller quantities which I needed for now. Quality and packaging were impeccable. That being said, in 6 months-a year when sizes stable out a bit I will probably order from Reptile Deli, as they are closer to me, and I have prior good experiences with them. Also, Brian mentioned that they are working on selling smaller quantity packages in the future for rats under size Medium, so that will be great as they do $25 flat shipping.
