so basically, the reason is because there are a lot of ignorant consumers. right?
I wouldn't say that at all. It just when people are busy buying lots of things/researching products and trying to keep track of prices in their minds, they start from the highest digit and work backwards. Often people's subconsciousness plays a trick on them. It's quite effective on most consumers, whether they realise it or not. No offense intended, but it seems odd to me, that someone would ask a question about something, that is marketing and business 101 and then call people who fall for it ignorant.
