Same here, I just got an RPi4B+ and started playing with it a little. I was curious about the eCommerce possibilities but to my surprise, I was not able to find much information on if it was ever attempted or how to make it happen.
OpenCart seems to be the most used in Open Source ecommerce solution but I am not planning to create massive eshop and I am not expecting a ton of traffic either, just would like to see if that can be done and up to what limit.
Hope more people are considering this.
