Is there anyway I can buy older shirts?

I want to buy “rain dance,” but it has been reckoned is there anyway i can get it?

There is a site called ‘teetrade’ where people put up tees to either trade for other shirts, or sell. The condition of the shirts varies - some are brand-new/never worn, some are worn… usually people the condition of the shirt in the description. So you can take a look there and see if someone has that shirt in your size up there, or look from time to time in case it appears.

Hope that helps!
