Hey Guys, I am new here. I am going to Japan to purchase a MBP in Apple Store. Because Japan dollar is cheap now and I can have tax refund there. I know that Apple Stores don't sell Build to Order macbooks, you can only buy BTO online. But in order to get tax refund I have to purchase one in Apple Store. And I really need my MBP to be 16gb ram. So my problem is: Can I order a BTO MBP from a Apple Store staff and pay for it on the spot so that I can get tax refund? Thanks in advance.
