Just to look at it from a slightly different angle, online commerce could actually be a tool to enable us to avoid servile work, and to avoid physical commerce (going into stores that have to have people hired to staff them, stock the shelves, clean up, and so on). Seen that way, it could allow us to stay at home, stay with our families, not have to be out in the world of work, and so on.
Seen that way, the only problem I can see --- and it is a considerable problem --- is that once you click and place the order, that sets into motion a chain of events which requires people to work immediately --- the Amazon warehouses are a case in point. Just because we can't see the person who is working, doesn't mean that they're not being forced to disregard the Lord's Day by putting in their own servile labor. (But a lot of people work at those warehouses out of necessity, the pay is fairly decent, and there may be few if any other jobs in that community that are as easily accessible. Frequently, in the world or work, you do what you have to, not what you'd prefer to.)
As a rule --- and I shall not dogmatize on this --- I do not engage in any online commerce from Saturday evening to Monday morning, unless it is something that has to be ordered and set into motion, to arrive as quickly as possible, such as necessary things for our home where I am caring for disabled parents, including a father who is gravely ill. It is the same as if he needed dietary supplements from Walmart on a Sunday. I do try to plan so as to avoid such shopping, but in circuмstances such as this, that's not always possible. Things come up. But if it's some widget that I don't have to have in a short time frame, then I hold off until Monday morning. That's the best way I know to deal with the conundrum of "is online commerce something that is forbidden on Sundays?".
