Canon Ixus 145: Just $19 at Kmart
The problem with items on sale is that you are forced to buy them even if you don't really need them. To put it correctly, the problem is our decision making. What would you do anyway, if the item is priced so low? Take the case of the Canon Ixus 145 camera. I saw it on sale at Kmart for only $39. Now add to that Canon's cash back promo of $20. Imagine just shelling out $19 for a Canon Ixus 145? What can an ordinary shopper do? Even if I have 5 of these already, I would still be buying five more.
