How to save up money as a teen?

Okay, so over the summer I'm trying to save up money to buy myself the Canon Rebel T3i or the Nikon D3200. Though, those are a little pricey. I was thinking of opening an Etsy shop, but there may be better alternatives. What are some good ideas for saving up money as a teen? I'm like 13 so I can't get a job. I need something else to do besides wash cars, open a garage sell, babysit, have a bake sale or lemonade stand which I'm too old for, or clean peoples houses.

Work for your siblings and parents.

Don't spend it.
