Market Positioning

Marketing positioning, according to the book, is when a business decides to establish a distinctive and a desirable position in the minds of the target consumers. Now there are many value propositions which a firm can use to position its product.
I will apply some of these value propositions to different products and I want your guys feedback on this application.
There is the more for more value proposition which is you get more and you pay more. Its best example is Gillette Mach 3 Turbo. You pay more and you get additional product features.
Then there is the more for less value proposition. Some of the old book shops in Lahore claim that you get the same quality of books there but at a lower price.
There is also the less for much less value propsition. There are some cheap hotels in Lahore which do not offer all the great comforts like other big hotels but these cheap hotels charge much less. What do you guys think about these applications?
