http://darkpatterns.org/maxcdn-com-may-2013/ - the $10 arises because the option for including edge servers in Asia is selected

http://darkpatterns.org/british-airways-distract-from-cheape... - I'm pretty skeptical that this had any malicious intent. It is showing the cheapest option in the column. Often the customer will already know which class they want to fly in, so it helps them to be able to skim down a column looking for the cheapest option.

http://darkpatterns.org/papa-johns-iphone-app-november-2011/ - I think this is seriously reaching. Every single pizza chain (both online & in-store) work this way. They do a lot to point you in the direction of their offers page too.

http://darkpatterns.org/directline-com-july-2010/ - Hilarious. If this website had any idea how much negative impact price comparison sites have had on car insurance in the UK, they'd be praising Direct Line for not lowering themselves to the tactics of all the other insurers (offering an incredibly unprofitable first year rate, then massively increasing pricing when you renew)

I'm sure there are more - these are the most clear ones after skimming through about half of the categories.
