PIE gives 50% of its own margin by default to the nonprofit you choose, or the share set in your agreement, and sends it at least once a year. It is PIE's own money: a share of what PIE keeps after its cost, not a share of the price you pay, so it can be small. Buying through PIE is not a donation by you.
