Advice on exchanging a keyboard

Hello. As I mentioned in my previous post, I would like to exchange my English International Keyboard for an Italian one. I guess the procedure would be to buy the Italian keyboard and sell the English one. However, I am based in Europe, and on eBay or other marketplace websites, I haven’t found many listings for framework computers, which would make it difficult to sell the old keyboard. Do you have any advice about this? The new keyboard costs €45, shipping included.
