Well, packing them carefully and shipping to Maryland may not be safe... As a flyertalker you should spend a few hours on ita matrix and your favorite OTA, book a ten segment mileage run trip around half of the world, take the macarons(!) as carry-on luggage, rake in a horrendous amount of miles, get upgraded on each segment, fight thegate lice, write/boast in a trip report, and incidentally deliver the macarons(!) in person to your sister-in-law....
