Have you noticed? Many stores attempt to sell you something right before paying for what you chose to purchase, videogames stores are a prime example fo this practice, when they ask you if you want to pay for some extra DVD damage/scratch policy, or house appliances stores that ask you if you want to extend your guarantee for one or two extra years, or even simply fast foods trying to sell you dips or sides and clothing stores that offer an extra item once you have reached a certain amount of money spent. Can you tell how incredible this strategy is? Can’t you already smell the money you’ll make? It’ s inevitable! You will increase the average value of each order in no time.
