Looking for source for Ergo lever shift cables

[elcolombiano]

My Ergo levers eat cables. The shift cables last about a year before they become frayed inside the ergo levers and have to be replaced. These cables should cost about $2-$3 a piece but I am having trouble finding them in the USA at any price. I can mail order them from overseas but I have to pay $20 to $30 in shipping costs.

Does anyone have a good source for Campagnolo Ergopower shift cable 2000mm at a fair price. I would like to purchase QTY: 10.
