Have you ever experienced that feeling when you wanted to buy something, but you couldn't afford it? You walked off and you passed the same shop every day, hoping that you could eventually afford it some day. How would you react when the shop put a sign "SALE: 20% OFF SELECTED ITEMS + 4% CASH REBATE"? You started to contemplate, but again you walked off, hoping that the shop will offer greater discount next month. The following week, the shop put another sign "SALE: 40% OFF ALL ITEMS + 6% CASH REBATE". Would you still walk off or jump into the shoppers queue?
I guess if you have been waiting to buy something that you always dream of, you will eventually jump at the opportunity.You will probably be more worried, if the items go out of stock, than getting more discount by waiting another week.......
