Redirect store to another page?

So I have a page A that lists all the items. I use shortcodes for each item to place buy now buttons.

I have another page called store, the default for marketpress. If someone clicks on the product in the shopping cart they get redirected to for eg. /store/product

Is it possible to redirect that to /page/cumtom-template-for-product. Where the original item was added to cart.

Also is it possible to redirect /store/ to /page/

The logical workaround for this is to make a template for the store page the same as page A , however page A is an archive of custom post types (where I use buy now shortcodes).

I cant think of a better way to explain.

Thank you
