It looks like I accidentally ordered two copies of the Starfinder Character Operations Manual: a new copy as part of order #3310994 and a lightly used copy as order #33461602.
I didn't intend to order the new copy as part of order #3310994 and would like to return it. I have a box and the invoice for the order. What else do I need to return this? Do I need an RMA number or anything like that?
