Most people by definition grew up in a standard middle class home. This means that money was always on the tight side and that means that people's spending habits are very conscious. But there are people who spend lots of money, way more money than what most people are used to spending.
I often see people charging way too little for their products. Remember if you want to attract 1000 people to your website it will cost the same. So if this case then why not have big ticket items when they get there.
Have you ever walked into a store and saw a special item for sale that was extremely expensive? This is done on purpose so that when a high roller comes in they can make a lot of money. Just imagine one customer buying something for 10 000 dollars!
