The best thing to do is to take a little computer know how to accompany you to go, mainly in order to cut the price, if the boss to see you don't know anything, then still have to slaughter you a hand. It is best to go to the big digital city to buy, assembly machine of each store source is almost the same, because generally in the past the boss just and you talk about the price, they are unified to talk about the price, and then go to sell parts of the place to help you collect goods, and finally assembled to you!
