I purchased three items in the marketplace before reading up on the full process (smart move, I know), and when the items were sent to my account, I closed out of the window where you... accept them, I guess would be the term for it. I only ended up getting one of the items, and now I can't figure out how to get the other two into my inventory. And I have no clue if I'm wording this well at all... I'm a super-noob at this whole thing, so I apologize. Thanks in advance to anyone who takes a look or helps.
