Double problem: mobile friendly site and shopping cart page duplication

[Timmmmy]

I have a website that has two issues related to SEO: 1) the main website (product.com) is not mobile-friendly and 2) I have a shopping cart site (buymyproduct.com) using Magento that basically duplicates our product pages that exist on the main marketing website. Uses click "buy now" on a product page and are sent to the checkout at "buymyproductnow.com".

The company cannot overhaul product.com website right away and our shopping site (buymyproduct.com) uses a responsive theme and works well for iphone and iPad so I am thinking of making buymyproduct.com the mobile-friendly version of our website by using a sniffer on product.com and forwarding users to the mobile friendly version.

If I add canonical references from the shopping cart product pages and articles back to product.com associated pages, will this lessen the blow to any seo issues? What other factors am I missing/need to consider

Complicated and painful. Maybe doing nothing right now is best.

Thanks for any feedback.

Frist you asked

"If I add canonical references from the shopping cart product pages and articles back to product.com associated pages, will this lessen the blow to any seo issues? What other factors am I missing/need to consider"

the answer to that is yes it will significantly help you. Is buymyproduct.com a completely separate domain from your other domain?  If is you are going to suffer some duplicate content issues until you address the response of phone/website issue I just built a e-commerce website based on Genesis framework with with Woocommerce I can tell you that canvas 5 the new one for woocommerce can essentially replicate any website out there with the developer for about $30 a page. And that site is 100% responsive I would use http://demo.woothemes.com/?name=canvas  with Woo commerce Magento is becoming a  dinosaur that does not perform well with SEO or on a quick server. Do yourself a favor and move to WordPress you'll be shocked at how good they are. I recommend the host like WP engine or zippy kid
