u can buy them for like 20$ theyre great but the catch is that the film is very expensive.
25$ for 8 photos. thats like 3$ per photo. and since the cameras are pretty old tech getting a good pic takes practise.
but if u rlly want to do it, then pls dont get ripped off and buy the camera at like a normal store cuz they rip you off by selling them for like 10x more expensive (seen it @urban outfitters)
u can find plenty at thrift stores or just on a marketplace website
