I have a solution for new forum users, but I'm not sure it would be will received.
If a "well established" forum user with a good rep wants to buy, would the seller be willing to ship first, then get paid after the buyer received the chips?
It's opposite the standard way things are done, and it makes the new users have to trust the buyers, instead of the buyers having to trust the new sellers.
It's just a thought. I'm curious if anyone would be willing to try this (from the buyer or seller side).
