Looking for Altoids Smalls tin

I am working on a cool electronics project (mini fluid simulator) that I am planning on enclosing in an Altoids Smalls tin. Since they are discontinued I cant find anything under $20 dollars.

I am wondering if there is any better way to get 1-3 altoids smalls tins in the US for cheaper. Or if anyone has a spare they sell for cheap. Honestly just one would be really helpful!

Thanks!
