To become rich is a common dream to every individual in the society. There are many ways in which one could think of to make themselves rich, if not at least richer. For most of us, the first "theory" (instinct) that comes into mind about getting richer would be - to cut expenditures. One such way to achieve it would be using of promotional discount coupons. At the first look, savings from coupons may seem insignificant, as discounts would usually range between 10 to 20%. A purchase of $10 worth of product would therefore mean a dollar off the total bill.

However, if such savings from discount could be extended on a longer range, it could mean much more. A classical example:

The annual savings from discounts would have amount to $1200 (15% of $5000).
 

Besides cutting expenditures, the second "theory" (instinct) that would surface in the mind about getting richer would be - to get more income. Once again, there are many ways in which one could achieve it. Reasonably speaking, savings from discount coupons or promotional deals could mean allowing consumer to buy more stuff for less. However, there's always a choice. Instead of buying more stuff with the savings accumulated from the use of discount coupons, consumer could invest and "grow" these savings to generate more income.

Using the same example illustrated earlier on,

The savings would have amount to $1236 (3%*$1200) a year later.

Like what was mentioned earlier, the figures would only mean much more in a longer period of time. However, the power of compounding interest is something that cannot be underestimated. Being said that, it must be noted that as consumers have different preferences and risk appetite, therefore the actual amount of savings and returns varies among consumers. In addition, consumers should always exercise their due care and diligence in the field of investment.
