DD (7) and I recently had a big clear out of her room, and got rid of a lot of her old toys games etc, either to friends with younger children or the charity shop. There were also some good bits that we sold on Faceboll locally - a doll’s bed abd some dressing up stuff. I gave her the money for her money box, £12.
DS(10) and I have now done something similar. He has a fairly big Hotwheels set that is complete, all works fine, which he has asked if he can try and sell too. It was a birthday present to him when he was 4 or 5, and cost £50ish. There is a very similar set currently on eBay for £25 buy it now.
DD is saying she wants the Hotwheelsto play with.
DS is grumpy because she’s denying him the opportunity to make a bit of money.
Would it be fair for DS to sell the Hotwheels to DD? At “mate’s rates” (he doesn’t know what the eBay one is listed at)? Maybe do some tasks to earn the payment?
