remove EXCERPT from "..store/products/" URL in MarketPress

Hi again,

How can I remove or hide the product EXCERPTS from the MarketPress URLs:

../store/products/

and

../store/products/category ?
../store/products/tag/ ?

I'm populating the product posts using a server side include plug-in (http://www.satollo.net/plugins/include-it) pulling in the contents from a file yet the excerpts field does not respond to this and displays the SSI plugin's short code instead; which does not work, hence this needs to go.

Many thanks

Ralf
