I do the same thing. No way will I pay $8 shipping for a $5 part. So the tendency is to place a decent sized order to justify the shipping. I work on a lot of games and order a fair amount of parts. You cant be expected to go over everything with a fine toothed comb. A quick check of parts shipped to parts ordered (make sure quantities are correct etc..) is usually all I do. Marco should have offered something. Personally I would have probably just soldered wires on as someone already suggested, but everyone is different. I understand where you are coming from OP.
