Thinking of returning something?

Tickets and Registration Fees

Full Refunds

Because we use your ticket fees to pay for supplies related to your participation, we cannot issue refunds close to the event.

If you purchased tickets to an event and are no longer able to attend, you may request a refund up to 7 days before the event, or within 24 hours of your purchase.

Partial Refunds

If you purchase a ticket and later find a discount code which would have resulted in a lower price, we will refund the difference if requested no later than one week after the end of the event.


As a general principle, donations are presumed by law to be irrevocable gifts. This is an important legal concept that, among other things, permits gifts to be tax-deductible.

That said, if a donation was made in error (such as a typo, double-charge, or a forgotten subscription) we can refund the incorrect charge within 60 days of the donation.
