The only link that I’ve found was for t-shirts, but it no longer works. I remember mugs being offered since I’ve joined, but I can’t find it now. So I don’t think they are still offered!!!
This link will take you to some Fluther stuff. I found the ad on Fluther under the “General/Everything” tab then look on the right hand side just under the “Popular Topics”. It says “Get your Fluther goodies”.Hope this helps
