A lot of you probably already know, but PSA for those who don't. Apparently you can only equip one at a time... If you're already wearing/using an exotic, [i] and don't have something to swap it with [/i] , then don't bother purchasing exotics from Xur. Just like I think there should be an 'are you sure' with every purchase, so that you don't buy things by mistake (I've bought shaders I didn't want by accidentally bumping the button), there should be a 'you already have an exotic equipped, are you sure you want to buy another?' I searched it and apparently people have been upset about this for a while. So yeah... Your attention please, Bungie... Edit 1: I've been around since year one. I don't grind like crazy. I work 6 days a week and am not a heavy gamer. My point is, there should be a message where it informs you, and you could choose 'yes, don't show again.' Edit 2: Thank you to everyone who's kindly helping bring me up to speed, rather than bashing me. I understand I should have known this by now, but various circumstances kept from playing much since March. So thank you for being kind.
