2018 has been pretty good so far, better than Jan-Nov 2017 at least. I also don't think Amazon has any impact yet. I still can't list anything there because they are still demanding UPC for everything. Their customer service told me to wait until they have a team who can take care of these things. I just hope that they won't start charging me the monthly subscription fee. With Amazon's 20% commission, I will also be increasing my prices when selling on Amazon.
