I'd recommend negotiating Amtrak Express shipping with any buyer:

You can get this done for $100 or so. Fees listed here are $69 for the first 100 pounds, 57 cents/pound after:

The caveats are: 1) recipient must pick up within 48 hours of arrival at the Amtrak station to which the items are sent. After that they charge you usurious storage fees. 2) You can't ship more then 500 lbs, per day, which this will not amount to. 3) each item must be less than 50 lbs and smaller than 36 inches cubed, which these wouldn't be. You can even get buy insurance pretty cheaply.
