Round up to donate during checkout

As a company that believes in the power of community and lives our Blue Cow Service promise, we often run fundraisers and donation drives to support local causes. We’d love to have a built-in option on our website and in DDMS that lets customers round up their purchases - or optionally donate more - during checkout. This would make it easier for customers to participate in the causes we’re supporting and would help us increase donations while reducing the need for manual coordination.
