I am building an ecommerce website that will have a XML feed from a wholesaler’s site feeding my site with 1100 products.  The products from the feed will show wholesale pricing.  I need to mark up all products by 100% to represent a retail price.  Does your cart have the capacity to mark these products up all at once or will I have to mark up each product individually from the feed?  I am trying to avoid this task.  Obviously it would require a lot of hours to do this manually.  Thank you.  I look forward to your response!
