or see if someone from the foundation will reply in this thread, but I don't think it will help.
The current distributors are the manufacturers and operate world wide. There are currently no wholesalers and no need for them. The pi is sold almost at cost, so they can't offer you any discounts higher than what you can get directly from the manufacturers. It doesn't hurt to ask, but I think your best bet is to buy in bulk and sell locally at a small mark up. Due to the shipping times and cost, it may be cheaper for people to buy from you than from the distributors.
