The Christmas season has arrived and that means it is time for people to watch their money if they plan to give to charities. Chelsea Dannon with the Better Business Bureau of Eastern Washington says make a plan before giving. Find causes and organizations in the community where the money will be spent to help those in need. Dannon says one of the most common scams of the season is the gas scam. People come up to people on the street or knock on doors, give a good story and ask for gas money. She says it is an old scam that has worked for years.  All people have to do is say "no thank you." Police say a man is knocking on doors in the Yakima Valley saying he has a delivery of wood, but that he has run out of gas and he needs money for gas to get the wood. It is a scam, so beware.
