This is a hugely successful template that perfectly and simply implements the idea of a “squeeze page”, in this case promoting a free offer for the price of shipping only. In reality, the cost of the item is actually included in the shipping cost. Provided the item is cheap enough (for example a short book which can be mass-printed for just a couple of dollars per unit), it can even sometimes include a small amount of profit, however the main purpose is to induce a ‘micro-commitment’ from the user (see "3:Affiliate Survey Funnel" below for more information on this strategy).
However, WordPress might not always be the right option for you. Although it is surely one of the most popular CMS platforms, there are certain circumstances where you want to see if there are better options for you out there! Especially if you are new to creating and running a website, it might take longer than you think to actually get things right at first. Although there are plenty of helpful tutorial sites like Beautiful Themes and WPBeginner dedicated especially for the purpose, sometimes it is a hassle.
