1. I don't see an option to select % for restocking fee when listing through bigcommerce . eBay has different option to charge restocking fees %.
2. Intentional shipping only gives me an option to select one country, while on eBay as subcategory of shipping I can select as many countries as I want.
Also limited options, to 3.
3. No option to select a BEST OFFER while listing on FIxed Price.
