Delivery is something no one ever give a thought about, but this portion might potentially cost you up to 25% of your entire purchase. After identifying the site that gives you the cheapest package, take a look at their delivery and compared it with the rest of the sites.  This would really give you an overview of which site is really offering the lowest rate. Some sites has delivery that would be free of charge if you purchase above a certain amount, so this is also an element that you can consider.  It is cheaper to spend on another blender, or just to pay for the delievery.
