In my Business Economics and Analysis class today at university I learnt that as a generalisation, as demand goes up so does the price of a product...that is ofcourse in a competitive market (which is what bannersmall is).

If demand was to decrease in fact, prices would drop in order for BM to stay ahead of the competition, and also make a sale.

I very much doubt that the price increase will affect their income for the worse. In fact I think it will do nothing but strengthen their market and also their brand name.
