Email collection for newsletters
In my option I feel that, websites should have an optional email capture. This way customers who are interested in our products can submit their email, and website owners can develop their email list.
It would be a great idea to add a section for a newsletter to SaleHoo stores so that people who browse through the SaleHoo stores can subscribe to a newsletter.
That way even if they don't buy anything at that time you can send them a newsletter to let them know of any store specials, coupons, etc.
It's like a second chance for the store owner to try to convince them to come back to the store to shop and buy from you.
