Great advice so far, and I wish we had stopped the madness sooner...I understand the frustration with import restrictions, but do you really need the iPhone 5c in blue when you already have the 5s? Our lawyer once asked us to get a purple camera for his daughter and finding it drove me crazy. A 16 year-old ended up with a camera ten times better than mine. Definitely be generous with your family and close friends (for one thing, you may be asking them for favors next time they go to Miami) and make everyone else pay in advance, have the item sourced in advance, and be ready to pay any extra luggage fees or customs charges. It should cut down on your requests, hassle and extra weight.
