I think Mikki is working on getting a few more merchants on board. From my conversations with him the hardest part is you will have to get the owner for 30 - 60 min chat about how it all works and what are the benefits and how they can use
https://isx.is/ to sell AUR for ISK.
If you know any merchants you can also help us do the heavy lifting by asking them if they accept Auroracoin and showing them how it works.
