I bought a pair from ebay.com, worked out fine. Just make sure that they ship world wide, or in your case atleast to whole North America.
i know that, it's just that i'm really anxious to bring out the fades. but i'll probably keep going for about 7 or 8 months
ya just letting you know so you dont get dissapointed
