Initially all the deals on Getsocio-powered sites were grouped by location (city). Recently we added another way to organize deals – categories
Now you can have multiple categories (and subcategories) on your daily-deal site. You may create any category, for example, "Food" or "Wine" or "Restaurants", "Massages" or "Beauty", "Theaters" or "Shows", or even more specific ones, like "Gadgets", "Home decoration", "Gold fish aquariums", whatever.
Categories are optional, so if you do not need them they will not get in your way.
Organizing your daily-deals by categories is a great way to further tailor your offers to each particular user. And your site visitors will be able to subscribe for updates in any particular category they are interested in.
