Really depends on where you are. I'm in toronto and pay roughly 1/3 of what you pay for in a store but some areas have more competition amongst other breeders and other places you're at the mercy of the pet stores. This is what I pay;

Pups: $0.90
Weaned: $1.10
Small: $1.50
Med: $2.00
Large: $3.00
XXL/jumbo: $3.50

Which is a little more than I used to pay but much less than the pet stores.
