This is I use my own custom shopping basket and credit card payment system that I wrote myself that goes directly to the Visa/MC and Amex processors.
DIY and you avoid all the ‘facilitator’ fees and state tax hits on small sales totals.
I think I may look into that. I am small as I hand make all my items (hats) so I can only make so many items in a year.
At least for the moment The facilitators are actually do the collecting because it would be an accounting nightmare.
