Let's say it is winter, it’s cold, and you don’t want to go outside twice a day to clear the snow from your driveway and sidewalk. Then, one day you open your mailbox and find an amazing offer: $300 to have the snow cleared twice daily throughout the by company.
That’s a great deal, so you call the number and a representative of the company comes to your door within the hour. He gets you to sign a contract, which requires you to pay half now, half towards the end of the winter. What happens is that you give him $150, but you will never see him ever again.
How to avoid: always chose your snow removers by checking the reviews and find out which reputable companies are out there. Alternatively, give up going to the gym and get plenty of healthy exercise shifting your snow.
