Email to a Friend
This is a great way to get extra promotion for you site, as when visitors are browsing your site they can simply tell their friends if they come across a product they think they might be interested in.
You can add a 'Email to a Friend' link on all pages within your online shop. When clicked the visitor can enter their friends email address along with a short message. A link to the product or category they were viewing is then emailed to the visitors friend.
