Price of Feeders?

I have a wholesaler near me with great wholesale rat prices:

$1 small
$2 medium
$3 large
$4 jumbo

Mice are 50 cents a pop no matter what size.

Mice are about $2 all sizes and rats are around $4 all sizes

I pay about 5 dollars for a big bag of weanling rats(Sorry, no mice :()

There's always websites like rodentpro.com that will charge about .30 cents for each hopper in a bag of like 100.
