What percentage of each sale goes to autism charity?

We usually send around 5% of sales to our partner charity, Surfers Healing, a non-profit organization committed to aiding children on the autism spectrum by providing surfing lessons in a safe and comfortable environment. It can vary up and down a bit depending what our expenses are that month, but at the end of the year our target is somewhere between 5-7% and as we grow we are hoping to get closer to the 7-10% range if we can afford it!
