I would like to buy two chipmunks, still haven't found any shop that sells them. Thanks

You won't find chipmunks in pet shops, anywhere. They can't be kept as pets.

This is an international site; mostly answered on the north american continent. Where did you get the idea that chipmunks can be kept as pets. Any pet expert here on AMHD will warn you that this is just not acceptable. Chipmunks are wild animals and should be left in the wild where they live and thrive.
