I sold a lot of houshold goods and underestimated the shipping cost by ALOT. Out of desperation I found this site online and was nervous but found that not only is it a great site that was able to find me a shipper with a great bid fast, the shipping service went exceptionally well. The uship site really saved my bacon in this case and I would recommend using it.
Obviously one should always check the shipping company's credentials before accepting bids but I had a very positive experience all around.
