hmmm thanks. so you are saying the markets module and stripe will handle all the refund requests?

I'd like to figure out the connect thing eventually, and take a percent as well, but I think i will have to come back to it as its sounding super advanced.

I just don't want to be besieged with customer service trying to figure out if people got their product or not

If you are using UNA Market - then the selling and any follow up correspondence or refunds, can be done directly between the seller and the users, there is no need for you to intervene at all. Payments can be handled via Stripe or Paypal (probably best options for US) Stripe Connect (which is complicated to setup) is only necessary if you wish to glean a commission.
