Behavioral Economics acknowledges that humanity does not consist of 'Homo Economicus' individuals, who act and make decisions under careful calculation and harm/benefit analysis, but of humans, after all, suffering from irrationalities and imprudence. Thus, they deal with numerous types of biases that lead to certain decisions. Which is the type of bias that best explains (fits) the following situation?

Martina wants to buy a new watch, so she visits a watch store in her town. She chooses one that she wants to buy, and the dealer says that its price is $200. Although she finds the price moderate, she realizes that it is way more expensive than 120$ she was willing to spend. As she did not find another watch, she left and returned a week later. When Martina revisits the shop, the dealer says that its price is now $150. Martina, very happily, buys the watch because she thinks that the watch is cheap.
