Saturday we had a yard sale. We got rid of lots of stuff and made a little bit of money to add to our vacation fund but the best part of the sale was the experiences the kids had and the lessons they learned.
Kya was my cashier, she spent the entire day giving people their change and never faltered. She had so much fun and felt very grown up. Jace declared himself in charge of "customer service" and helped me bag things for people and told everyone "Thank you, have a good day." He also kept track of how much money was in the box, how much was profit and how much 15% of that profit would be since that's what he and Kya got to keep. (I made it 15 instead of 10 to make the math a little more complex, hehe).
They also learned the value of decluttering. At first they weren't excited about the prospect of giving up some of their things but once money was involved they were willing. The unexpected (at least for them) benefit of having more space that is easier to keep organized was a welcome bonus.
But perhaps the best thing they learned was that they spent a lot more on some things than they got back, some were practically given away at such low prices, and some didn't sell at all and were given away after it was over. Kya commented that she was going to be careful how she spends her allowance because when you're done with things you just don't have anything to show for the money you spent. The value of spending wisely. THAT was a great life lesson.
