Do you know if there is any shop out there that has Bitcoin merchandising or Alts stuff? I assume that many of the logos are registered brands, but not so sure about BTC.
There is no stores kind of that you are looking but if you wish to use the bitcoins alone to buy the day today stuffs in e-commerce you can use the purse.io site. I hope you may aware of it. Still wanna explain about the offer to use the bitcoin to buy the products.
This site will direct you to amazon e-store you can buy anything with BTC. If you use bitcoin as a payment mode they will offer you 15% flat discount on all the products. You can gain some reward points for the every purchase done via purse site. It would help you in your future orders.
Are you sure? I just found this site
https://allthingsdecentral.com but not yet test it out.
There's a lot of merchandise available to order , not sure if they are legitimate or not.
But Yeaaa unfortunately , there's lack of interest on that kind business for some reasons, no wonder the existence is hard to find it for common people.
