With warmer temperatures here, the Better Business Bureau of Minnesota is reminding you to be alert and have a plan when it comes to door to door salespeople.

While most salespeople operate honestly and represent respected businesses, there are others who are looking to pull off a quick sale and move on. The Better Business Bureau recommends you follow these tips on how to handle those you may find at your doorstep.

Ask for identification and a license
A seller should provide you with information, including an ID and business card.

Verify the salesperson and the company
Get everything in writing including price, contract duration and any other terms. Tell the salesperson you will check it out and get back to them. Then research the company and contact them directly to verify the salesperson is an employee.

Read contracts closely
Make sure you understand terms and conditions before signing on the dotted line.

Stand strong
You should also watch for and stand strong against pressure sale tactics. If a salesperson refuses to leave, tell them you will call police and do so if they don't leave immediately.

Know your rights
The Federal Trade Commission's three-day cooling off rule gives a customer three days to cancel purchases over $25 that are made in their home or in an off location that isn't the seller's place of business. Along with a receipt, salespeople should invluce a cancellation form customers can send to the company. Companies must give customers a refund within 10 days of receiving a cancellation.

Do the math
Beware of contracts that ca cost you in the long run. Be aware of magazine subscription costs that can add up fast.

Discount asphalt?
Steer clear of asphalt firms that say they have leftover supplies from another job. This is usually a scam, professional asphalt contractors would know with great accuracy how much material they need for a project and wouldn't have extra.

If you have issues with a door-to-door salesperson, you can file a complaint with the BBB on their website. You can also contact local law enforcement.
