A customer asks to return shipped items of an order from My Account, inside the return window, with a reason per item and a refund or a replacement. Sales > Returns shows the request with the items and the conversation; the store approves (the customer gets the return instructions), marks the items received, refunds through a credit memo, or rejects, with a message at every step. Both sides can write on the return; every step sends an email.
A return in My Account after the store approved it.
