At my school kids always sell stuff to other kids, and what's the one thing kids always love? Candy! Go to a big Costco or bargain mart and pick up a twelve pack of skittle for like 6 bucks, go to school and sell the skittle packets for 1.00$ each.

Triond

Triond is a really helpful site which is one of my main money makers, you get paid to create articles about anything or publish pictures or record a solo anything you want, just create an account on triond.com and start publishing today!

Treasure trooper

treasure trooper helps but isn't as good as Triond, you get paid to fill in surveys and clips and stuff, the pay is good but you end up losing more money than you get as the surveys require items you need to buy.

Lawn mowing

A bunch of kids from my school do this too, it is hard work, but good pay, however if you want the money to buy stuff online, triond is the site for you.

Dog walking

This is a job not many people do anymore but it always works on your neighbor. If she is close to you(relationship wise) and from the cash you make you can tell your parents to transfer it into your pay pal account if you want to buy a runescape MEMBER SHIP OR SOMETHING.

Allowance

We all know this way as most kids have one. An allowance gives you the most money you will get out of anything (except merchant in real life, the kids at my school make 100$ a day if there lucky) but it takes time, lots of time.
