How to Remove /store/products/ from Marketpress URL

I'm thinking of going back to Market press and I'm using another eCommerce theme and my urls are indexed and or posted elsewhere and don't want them to change.
I have Marketpress on my test Site (multisite install) and on an Add on site the url for a Product is
domain.com/store/products/nameofproduct/
How can I remove /store/products so I end up with domain.com/nameofproduct/
