USB Flash Drives

How much of the purchase price of the USB Drives goes to the portable apps project?

I wish to know how much of the USB drive price goes to the Portableapps project. I sent in a donation, then it occurred to me, if the majority of the price of the companion USB drive went to the project, then I could buy the drive and most of what I spent would go to portable app development.

Since I don't really need another USB drive, there would be no other reason to actually order one.
