Allow Exchanges in fee tier

I have recently ran into a situation where customers realized after the fact that they ordered the wrong sized item. On fee tier, there is no exchange option, so the only action available is to fully refund the purchase and then re-charge for the new item, even if there is no cost difference.

Exchanges feel like a standard part of doing business, much like taking payments and issuing refunds, and does not feel like enough of a value add to be placed behind a paywall.
