are they just bottles or is there beer in them? make sure they use lots of bubble wrap and stuff whatever is needed in there until there's absolutely no movement in the box. technically, it's illegal to send beer via USPS and against 'policy' to do it with UPS/FedEx, but people still do it quite often. i'd say go with one of them. i sent 16 beers to a friend in NYC recently and it cost me about $20 for the actual shipping and another $10 or so in packaging material. so, i would guess you're looking at $50 depending on what shipping option you take.
