What happens if I need ot return something to Amazon after the 30 days?

Ladies I purchased two items (same Amazon order) and they were faulty… it was past the 30 days return window with Amazon so I filed a dispute with my bank and Amazon emailed me today about it. I told them about the items and now I’m waiting on a response. Has anyone done this and what happens usually?? I’m willing to ship back the items but it’s been past 30 days.
