CES 2003 show: do they sell products?

I have never attended a CES show, but have decided to attend the next one, even if this means crossing almost the entire globe to reach Las Vegas.
I'm thinking of upgrading my cables and I'm wondering whether exhibitors do sell their products there and if at promotional prices.
I'm from Mauritius and there are no high end dealers in my country. Customs regulations and long postal delays from the US to my country disccourage me from purchasing goods on trial basis.
Many thanks
Officially, there are no sales. However, some(!) exhibitors will sell displayed merchandise at the end of the show to avoid costs of return shipment. Catch as catch can.
