     In times of economic downturn, many people start to look for ways to reduce their household budget

and save extra cash. Living a thrifty (节俭的) lifestyle does not have to mean doing nothing.   1   Here are some tips.

     Track your spending for at least two weeks. You won't really know how to live a thriftier lifestyle until

you know where your money is going. Write down every time you spend money and take a look at it at

the end of the month.   2

you can compare prices from more stores in less time.   3  Combining producers' coupons (优惠劵) with

store discounts can lead to major savings.

     Turn off the lights and other electronics in your home when you are not using  them.   4   Leaving

electronics on can use a tremendous amount of extra energy, costing you money.
