I've never ordered pre-owned games from BB before. I know DLC codes are probably not included but what about manual and overall quality of the discs?
Whenever they get trade-ins they usually have them shipped to get the CD cleaned/buffed before they shrink wrap the games before they are redistributed to stores.
That's what has been implied.
The discs I've received have all been in good condition.
All the games I've ordered have come in a case with artcover and manual but I'm not sure if it's standard or I got lucky since I know I see a lot of copies in store that have that ugly printed cover
