That depends on the shirt! Each shirt purchased completes a tangible task for the specific cause that shirt represents. That simple. The great thing about This Shirt Helps is that you CHOOSE your cause and that's where the task takes place. At the time of checkout you choose which cause your purchase will benefit. And if your cause isn't represented, submit it to us -- we will be adding new causes as fast as possible. So if you have a worthy cause that isn't here yet, it will be. And we've got a running ticker so you can see what we've accomplished so far.
