Could our brand loyalty drive up the cost of shopping online?

 One web entrepreneur, Alex Gannett, founder of CampusSplash says that 2012 will be 'the year of behavioural pricing' - a new type of e-commerce, where prices will be tweaked to include what customers are willing to pay. Gannet writes, 'This year will mark the end of static pricing. The use of your tweets, credit score, and web history in e-commerce pricing is frightening?but ultimately unavoidable.'

Though [erhaps a more reasoned response is at
http://socialmediainfluence.com/2012/01/27/social-commerce-spotlight-will-behavioural-pricing-drive-up-the-cost-of-shopping-online/ 
which points out :  "behavioural pricing has existed (albeit in more simple forms) for hundreds of years: physical stores will alter their prices based on the demographic of its patrons; seasonal items are priced according to demand, and sales and offers are designed to appeal to certain markets. "

So while I think there is a touch of 'scare mongering' in the Daily Mail article (no surprises there) it is a relevant issue, given the information we share to retailers, often unwittingly, online.
