Dear Sir or Madam:

This certified letter is to cancel the order I placed on ___________ with one of your door-to-door encyclopedia salesmen. He was extremely pushy and I acted impulsively. After he left, I regretted my action.

Luckily, a friend pointed out the law stating that there is a three-day "cooling off" period in this state in which buyers may cancel orders placed with door-to-door salesmen. I checked this information out with the Attorney General.

Enclosed you will find a copy of my contract. I have also told my bank to stop payment on the down payment check.

The above mentioned actions should conclude this matter. I regret any inconvenience that I may have caused your company.
Sincerely,

______________________________________
