When you are for the search of a good deal on a product you are likely to end up spending quite some time to find it. Now remember hya time is also worth money. Think of the opportunity cost: what you could have done with that time instead. Therefore, spending too much time on finding the best deal may simply not be with the savings at the end. You’ll have to find a balance between the time you think is worth spending and the money that it will save you.
