I was ordering from Big Cheese very faithfully, but they've been completely out of frozen rats for a couple months now. (They do still have mice, last I checked.)

So I tried Rodent Pro this month, but I wasn't thrilled with them. There's something wrong with the way they pack their dry ice... there was still plenty left, even though the box took several days to get here, but it was all in one corner. The rats farthest from the dry ice had started thaw, and one of the bags smelled like carrion and rot when I opened it. I had to throw out some of the rats. Ugh.

I feel like they could fix this problem with better packing... in the mean time, I'm trying Mice Direct next...

Loxahatchee gets good reviews, but their shipping is INSANE. Especially if you're doing small orders.
