Warm weather is here which means door-to-door sales crews are here, too. But what they’re selling isn’t always legit.

Be cautious anytime a stranger comes knocking, especially if the visitor is trying to sell you goods or services.

Be wary of contractors who say they stopped by because they just happened to be in the neighborhood. The good ones are usually too busy to roam around in search of work. Also be on guard for high pressure tactics to make a quick decision for a steep discount and requests for payment upfront.

Your best bet is to proactively seek out services if you need them, versus reacting to an unexpected sales pitch. It’s always OK to explain you don’t do business at your front door (or to not answer when strangers knock).

Be a fraud fighter! If you can spot a scam, you can stop a scam.
