Just to everyone to know, I placed an order for 1 GPU (as a test) with this seller. I am going to use PayPal. I am waiting for his reply to continue trade.
Update:
I received PayPal invoice from seller. There was no my company name or address, I asked seller to update invoice and send me again.
Update:
I've ordered 1 GPU. I received PDF invoice and PayPal's request for payment invoice with all details I needed. I paid full amount on PayPal today. My GPU is supposed to be shipped around next Friday, 23.02.2018.
Will update here once I got any more news.
