Have you ever heard of Groupon, LivingSocial, or any of the other hundreds of daily deal sites? In short, sites like these offer their members steep daily discounts at local restaurants, stores, events, photographers, spas or nearly anything you can imagine you can buy. A free membership to a site that saves you money sounds great to us here at 9 Year Mortgage! But as always, advertisers are tricky and make it so easy for us to look past some of the little details that could cost us some money or time later. For this reason, 9 Year Mortgage has configured a list of 10 things you should know about daily deal sites that they won’t tell you themselves.
