I have three (maybe more) dealers who are willing to sell 50 tech for 3million. Send me a PM with your information and I will forward it to the dealers. I will be one of the dealers. I have a single slot open at this time and another two will open up later. We will potentially fill three to all five of your aid slots very quickly. Send PMs in game to me, nation link is the blue image in my signature.
As soon as the sellers are contacted, they will send you an aid worth 50 tech right as soon as they are made aware. You should not have to contact the selling nation, I will handle all of the logistics. However, if there is a problem, or you wish to do long term deals, contact the seller yourself and forward a copy of the PM to me.
