Unfortunately once you submit an incentives order in Ethnio, we send those funds to various payment providers and the money is spent. That means you cannot edit email addresses, amounts, or re-issue.
Think of it as sending money via PayPal, which is one of the many providers we use. After you click "Place Order," the money is shipped off to another institution and Ethnio cannot issue any refunds.
There's a warning at the top of the Place Order page for reference
