About Shiping cost:
Default USD$6 is for just one unit item; Shipping cost of one unit item is USD$3 if you buy 2 units or more.
About CPU:
You must wait one or two minutes when you use CPU first time,because mainboard need check all parts third times.
Don’t worry about all things because I will test and protect it before shipping.
