Im interested in your situation op. Mine are too young to make that choice but I want to set up the financial situation in our house so they are motivated not to do that. Not sure how though.
My son is now 25 but back when he was 9 he used to pester me every week for a computer/console game, they were around £35-40 each back then and as a single parent I couldn't afford to give in every week.
A friend told me that she gave her daughter (same age) an allowance of around £50/month for doing some chores but that she had to buy her own clothes (except school uniform etc), games, toys, books, sweets etc, out of her allowance and that it worked really well for them.
I talked to my son and explained how it would work and we agreed to give it a try.
Having helped around the house to 'earn' his allowance has given him very useful life skills too, including cooking, using the washing machine, dishwasher, vacuum cleaner, duster etc, etc.
Sometimes when we went grocery shopping he'd conveniently forget to bring his money out with him, I said that I'd pay for what he wanted but he'd have to pay me back as soon as we got home, in the beginning he thought he'd get away with it but soon realised I was no pushover. I did occasionally deliberately under-calculate my maths a little in order to give him a little treat but it didn't happen very often.
By the time he was 13, he was fully aware of how much things in life cost, he realised that he could buy a £10 pair of jeans in the supermarket or a £60 pair with a label, they both served the same purpose and one meant he had money to do other things with.
I also talked to him about household expenses to give him some financial education, not least because when his father and I split up, just before the divorce was finalised, he ran up almost £50k of debt, gave up work and told his creditors he couldn't afford to pay them, they all came chasing me as I was working and still legally responsible for his debts. My son has grown up watching me scrimp to get by because I've been struggling to pay off his father's debts, I wanted to make sure that he didn't get himself into similar financial difficulties.
He's now 25 and has a reasonable salary, he has savings and buys nice things but he's always on the lookout for great deals, voucher codes, sales etc.
Some people would say what I did was wrong but I needed the help as I'm disabled and he wanted to help, he got something worthwhile out of it and he's actually thanked me for teaching him all these skills, I'm a very proud mum!
