When you buy a product for $ 100 at a retail store or online, its real value is only
$10- $40. This is due to intermediaries between buyers and manufacturers.
Intermediaries are certainly an additional expense. They try to sell low-priced products as expensive as possible.
Why is retail so expensive? Mostly because it is not known which product can be sold in what quantity and when.
If consumers tell you what they are going to buy after a month and pay for it in advance, you can sell any product much cheaper than another. All you need is a place where people can come together to buy the product they want.
