Does not change the price if you upload github files yourself - the price is calculated by PCBway, not Soyovan. If you order just 5 PCB, price per PCB is high. Selecting 100 it is less than $2 per PCB. Setting up the production is the costly factor (and testing). Thats the reason groop buys were invented.

Actually Soyovan is not profiting - it is simply the price if you order a smal number of smal 4-layer boards on pcbway. pcbway chechs every order, and the checking part is independend of the number of boards you order - as setting up the production is. Try it yourself: 5 boards are $130, 100 boards are $180 and 1000 pcbs are $560 (so 56 Cent per pcb). Wouldn't call that to much. Soyovan just uploaded the settings for making ordering more easy. Only "profit" is a discount when ordering PCB's for himself. But still you should organice a group buy, so you get a resonable price per PCB. Not Soyovan sets the price, it is PCBway, depending on the number you order.

I am attaching your information note to the page, thank you.
