How do I open a new window in marketpress and remove the price


I have not selected listing s only in marketpress as some of it is affiliate links and some actual products or downloads,

Is there a way that when they click on the link it opens in a new window or tab?

Also for affiliate links is it possible to remove the price as in most cases it depends on the product or package they pick, if not is there a way to change it to price from?

KInd regards
