Apple has added links to allow people to share products via links on Twitter and Facebook, reports MacRumors. The upgrade to the store appears to be the reason behind its downtime this morning.

The links appear via a drop-down menu that appears when you click on an arrow next to the ‘Select’ button on a product page. Currently only the Mac Pro product section has the new sharing buttons enabled, but it seems likely that this will be made a site-wide change shortly.

Currently Apple’s iTunes Store offers similar sharing options when viewing a song, album or video, and the App Store also offers a similar ability to link to Facebook and Twitter.

Apple has been making moves to embed social sharing deeper into its products, with the integration of Twitter into its iOS software at a system level a prime example.
