Marketpress Shopping Cart Widget

Hi -

I'd like to be able to hide the MarketPress Shopping Cart widget from displaying when the user is on a Shopping Cart details page (i.e. URL/store/shopping-basket/) so that the Cart isn't duplicated. Is there some logic that can be used to hide the widget on this page?

Likewise, I'd like to hide the Shopping Cart widget on the Checkout page (i.e. URL/shopping-basket/checkout/)?
