Hello Guys im planing to travel to USA (Miami) and planning to purchase latest iPhone with 128GB. 1-I wonder if there is way to purchase an iPhone without Tax. (macmall doesnt sell iphones ) 2- most importantly do you buy Apple care + ?? I wonder if iphones battery dropes 80% or more in 2 years to be able to replace it using apple care+. conditions -> "for batteries that retain less than 80 percent of their original capacity." Does anybody have experience with that?
