I know most families have a budget that includes a portion for entertainment. If you put our entertainment portion on a pie graph you wouldn't even be able to see it. Mostly because our entertainment is free and the little we do spend is so little its hardly noticeable.
Our biggest entertainment expense is Red Box. $1 a day. And even then half the time its free with codes. Which reminds me I really should get Cloudy with a Chance of Meatballs before my code expires. I saw a new location yesterday, outside the Denny's. Dinner and a movie takes on a whole new meaning. We rarely go see movies at the theaters. For the kids birthday we let them pick one thing they want to do just for themselves. Sometimes they pick a movie. Last year the Dh went to Cloudy with 2 of the kids for their birthdays and Ice Age 3 with another one. But that falls under the birthday budget, like cake and ice cream. If the kids want to see something not during a birthday they have to save their allowance. So we only pay for the adult to go with them, or sometimes they go with a friends family.
Most of our trips are homeschool related so that comes out of the school budget. Like the History Festival. We don't do concerts. The kids can't even stand it when a car drives by blasting their radio. Every year my grandparents send us money for the kids for Christmas which we use to buy a year pass to the Zoo. So again, to us, does not cost anything. We have Culture Passes here, which is free admittance to places like the zoo, the art museum and the science center. You can only get so many so we do have to pay for the other kids.
So there are lots of ways to entertain ourselves inexpensively. Especially if you are just sitting at your computer watching you tube videos.
