I too want to have a shout out for Perfect Prey (sorry for stealing your thread, but figured it be better than making a new one for the same place lol!) As mentioned above, everything was frozen completely solid, the rats were very clean and a good weight, placed on styrofoam trays and had all their tails and legs. And like the OP, there were no variants in size in my order.

I ordered 10 medium rats and 25 medium African Soft fur rats. Everything was spot on. I guess i live closer to them because the shipping for me was around $29 for one day shipping. I ordered Monday and got them on Tuesday, I didn't get to see the packaging because i was at work but my dad said it was very well packed. So far, I will continue using them for my feeders.

I was very happy with my order as well, great feeders, great price, easy to use site. If you live in Florida, give them a try.
