Hey @1984 Pro thanks for sharing your feedback.
A few questions:
1) which seller are you referring to ?
2) how do you feel "shipping, communication, billing" to be constraints?
3) we offer 2 payment options on the bazar (stripe & paypal), these platforms do not cover all of the world and we are sorry for these countries, but this is outside of our current scope of the bazar
Looking forward to hearing more from you
