Alternatively, create an Apple ID in the US. You can probably do it using a VPN, but of course, you need to have a US credit card to purchase. I have that so no problem, but lately I've been using discounted iTunes cards. They appear every now and then on Bestbuy.com.
I too suggest that your purchase it in the US. The Apple Store online will not ship internationally, but other vendors may. If you have someone you know here with an EPS account, that's probably the cheapest way to go. Shipping would be around $15, and you will then have to pay 16% ITBIS. The Apple Store online does not include receipts with their shipments so that could be a problem if customs value it at the price in the DR. Well, that is if they know what it is. I purchased an iMac a few months bak and since they didn't know what it was, they charge me ITBIS based on the price of a cheap monitor. I didn't complain.
