We are moving from Madrid to Portland (OR) in the US and need to ship a few boxes (20-30 kg each) to the US . Does any one know of a shipping company that can deliver these boxes at a price which is less than excess luggage by airline (150 euros)?

thanks for your help

A company called TNT I think can help http://www.tnt.com/. ask for slow snail delivery. you may have to ring them and find out. basically the boxes will sit in the ware house until they get free space on a ship to send it to the other county. I used it in Australia to Ireland about five years back. It took months but Every thing was as i packed it when i received it.
