you could also find another breeder who is local
If i ever get surplus of my rats and decide/find someone to buy them i will just sell them at the price i would get them for

pinky .50
fuzzy.75
hopper 1.00
weaner 1.50
small 2.00
medium 2.50
large 3.75 (i would go to 3.50)
jumbo 4.00

prices around where you live will probably be different, these are just in my area
