Schoola is an innovative new website and app that sells gently used clothing to benefit schools.
Here's how it works.
Register your child's school at schoola.com.
Request a donation bag and fill it with outgrown clothing in good condition.
Ship it back to school for free.
They'll post photos of your items for sale for other people to buy.
When a purchase is made, forty percent goes back to your school.
Shoparoo is a free app for both iPhone's and Androids that rewards users for submitting photos of their shopping receipt.
Based on how much you spend Shoparoo rewards points.
Points that add up to real dollars.
It works because shoppers sell anonymized receipt data to market research companies.
And since they make a buck, they give some back to schools.
And finally, there is goodshop, a website and app that will donate a percentage of your purchase to a charity or school of choice.
When you navigate your favorite online stores through them.
When you connect to your favorite store through Goodshop they get a referral fee which they split with your charity.
