I believe you are addressing two entirely different topics and intertwining them unneccessarily.
1) BP/W costs to profit margin.
I'd start with the BP. A back-plate made of stainless steel and cut in smaller numbers is going to cost quite a bit more than than the common injection-molded plate that is turned out in the thousands. I'll leave the rest to itself. You can figure it out.
2) Internet sales
There is already quite a lot of internet sales. If you failed to look around at Crazy John, or DSS, or any of the other online sources of BP/W that is hardly my problem. It exists, you are apparently just unaware of it.
