So the mouse I'm using right now(mx518) is slightly broken. The olny problem is that I can't click and drag on anything. Its not a huge issue in most things but it pretty much kills my gaming. So logitech is sending me a new mouse but it will take two to three weeks and I really can't wait that long becuse CAL is starting and I need to play. So do you guys think I could go somewhere buy a mouse open then return it for full price after getting my new one or take the new one they sent me and use the reciept and get my money back with that? I really don't want to waste $40 but at the same time I don't want to wait. Any ideas?
