Small, cheap, standard escrow.
A first order with any vendor is really a test of whether they do what they say. Keep it small and cheap, use standard shipping and escrow, and encrypt your shipping address to the vendor key.
Read the vendor page. A low dispute ratio and a solid deal count on recent orders is what you are looking for. The right size for a first order is an amount you could lose without it mattering.
Encrypt your address to the vendor's PGP key before pasting it. Leave escrow standard and do not finalise early. If something goes wrong, you open a dispute, which is the path finalising early would remove.
