Yeah, most of the games I've gotten have been marked "refurb," and clearly buffed. 75% of the time, you won't get a manual or case either.
I've had MANY many cases where I've gotten the either the wrong disc or no disc at all inside the case! They're quick to refund in that case, but it's still frustrating.
Only order with the assumption that you'll get a disc-only refurbished game. Anything beyond that is just a bonus.
