There are there business models. Car boot sale/bag sale, shop and website/warehouse
A website is like a warehouse. Your life goes on as income streams in. You don’t have to be physically there. A website will advertise you/your product to the whole world. A car boot/bag seller only sells to friends they meet. Try selling to strangers from your bag and you could get into trouble. A shop owner sits and waits for customers. Which one do you want to be?
