Here's what I use about, I'm in mn an not many other people around me sell so.
Pinkie $1.50,Fuzzy $2.00,Pups $2.50
Weanlings $3.00,Small $3.00,Medium $4.00,Large $5.00,Jumbo ask me bout them. But I tend to give people deals an randomness it's based off this tho. An when people buy pets they get 2 for 15$ if their extra fancy or hairless 2 for 20$
