Having come from a council estate, there is a certain mindset behind getting a deal for everything, making your little money go as far as possible, buy one get one free, or discounts on anything, or coupons to get into restaurants or discounted vacations, or companies that "get you deals" on all your electric, gas, TV, internet bills, 8 packs of cheap beer, etc. are all seen as victories and you are crazy for not taking advantage of them. There's an emphasis on getting more quantity for less money. That's easily exploited.
