I've read results of research when they put sensors on shoppers' heads to measure the agitation in the 'fun zone' of the brain, in order to see if shopping was indeed fun. It turned out that the moment of ultimate satisfaction was the moment of making the decision to buy. What's more,people who decide to buy but changed their minds have MORE fun out of shopping than people who go ahead with the purchase, because they don't feel the guit and remorse about spending too much money!
