AfterShip Returns & Exchanges

I don't have lots of returns, but when I do, I need the process to be easy. and fast, and to keep my inventory accurate. AfterShip allows me to connect to Postmen, where I can buy a shipping label and send it to my customer automatically. It saves times and headaches! I just wish the clients could select the exchange items on any plans. I am on the free plan and this is not possible. F For me this is a feature that should come with a returns app since when customers exchange items, they actually need to exchange it with something else. Having very few returns, it does not make sens for me to upgrade to a higher plan yet.
