Feeder prices around me are ridiculous! Luckily I've been able to get some at wholesale through the aquatics store I work, one place we order from also sells feeder rats/mice and other pet "small animals" to petstores.

Mice prices locally to me are:
Pinkies: $0.99
Fuzzies: $1.29
Hoppers: $1.69
Adults: $1.99

Rats for either frozen or live:
Weanlings: $4
Small: $5.99
Medium: $5.99
Large: $6.99
Jumbo: $8.29

With the prices of feeders around me, I've broke down and I'm going to try my hand at breeding ASFRs (for hopefully a reduced smell) and regular ol' hooded rats at a minimum.
