You can order at Amazon.com using locally-issued credit cards like VISA. I have the dvds shipped by Amazon or Amazon third party sellers to my relative's address in the U.S. (billiing address is still my billing address in Phils.). My relative packs all the dvds in the smallest possible box, and sends it to Johnny Air Cargo in N.Y. I pick up here in Megamall.
You'll find out the shipping rate from Amazon to relative's U.S. address before checking out in Amazon. Shipping rates from relative to JAC N.Y. available thru USPS web site. JAC N.Y. to Megamall shipping rate is the discounted Pinoydvd rates.
Best way to learn is to try. Sometimes you're lucky, sometimes you're not so lucky, on the quality of dvds you get. Good luck.
