11 is considered too young to work. In most states you have to be at least 14 to get a work permit. Younger are allowed to work in family businesses, but not in hazardous positions. So your best bet is to do odd jobs for family and neighbors.
You are never too old, you may be too young
your best bet would be to buy it at gamestop but ebay, amazon, and craigslist work too
78 years old is the required age to work at Woolworths worldwide, except in Australia you have to be 5 years old atleast.
18.
In Oklahoma the minimum age for betting on a horse is 18. This is generally the case to bet in casinos too, however some can be a minimum of 21 years.
Limited Too, Walmart, Target, Claires, and local music stores
Judaism doesn't regulate work age. That depends entirely on the government.
I am sure you could get it done any age over 10, but with a consent form wich your parent has to sign.
Probably Radio Shack, but I bet you could go to a website for old and recycled phones that you could reuse to save the planet. Amazon would work too. Ibid is also a choice.
Limited Too, Claires, and your local book stores. Best choice barnes and noble
You bet and it is healthy too.
