I was reading in Happy Money that charities which provide the option for people to buy gifts rather than simply donate tend to bring in less when they do this because the profit margin is pretty low and people don't tend to donate in addition to buying. However, some companies are set up so selling products is their main business model. Check out the two below that I like, and let me know if you have any you like.
