i buy from a local guy and tell him the weight i want and he gets me what i want. i will never buy from another guy.Rat pinks are .50small rats are $1.00 and when i say small im talking 30g-55g. anything else i am unsure of.local store charges 1.25 for pinks and 1.75 for small/weened and good luck. you will need a weenling and get 2 around 30g and one around 50g. I am unsure of anything else yet because i have yet to get there.
