Not a long back posted how online coupons increased our spending. Since then we have learnt to use coupon in correct way. One example, every Friday night we go out for dinner, sometimes just two of us, sometimes with our friends. We like to try different cuisines and restaurants. Today we combined saving money and experimentation by having an account with restaurant.com, where we search for great deals on great restaurants, every Friday.
Also, recently I had to go for car servicing, regular price in our area for that model was $40+. Upon searching in our mail box I found a 10% off coupon which reduced my servicing expense.
