It’s very simple: imagine two car dealerships, both sell “cars”. One dealership sells you the normal loaded car. Other sells you a cheap “basic” version of the car, without the “non-essential” parts, e.g. windshield, parking break, … (which of course they say you can purchase later!). So the second car is cheaper – and you buy it, but very soon realize that it is very inconvenient to drive in the rain without a windshield, or to leave the car on the hill without parking break 🙂 You go back to the cheap dealer, purchase the missing parts – hey, it looks like now you paid the same or probably even more comparing to what you would have paid to the first dealer… 😉
