Hello, I have a quick question, I will be purchasing a Maxed out 15 inch Retina MacBook Pro (2.7GHz, 16GB RAM, 768GB SSD), since tax free weekend in NC is coming up, I have decided to wait until then, but something just occurred to me, it only meets the $3500 ($3454) limit when I put in the Education discount (I am eligible for this by the way) otherwise, it costs $3750, does the tax free apply to the computer after the EDU discount, or before.
