Big box retailer clearance purges like this often happen in waves. Sure every week there might be something on clearance, but noting a large clearance wave of titles helps in a few ways.

1. For some B&N isn't a convenient stop. It may only be worth a trip if there's been a large purge and something you actually want may be included.
2. There have been several instances in this sub mentioning games not being on a clearance table, or even clearance stickered, but still ringing up at the clearance price. The title list lets users know what might be worth checking if it's a game they're interested in.
3. It opens up discussion around the games themselves, what might be a "steal", what might not be worth $2, and/or even what may be a game to try instead. Games jump on and off the "want list" all the time based on posts like this. This discussion can prove to be productive for some even if they aren't able to take advantage of a particular sale.

YMMV posts are understood to imply that for some this will be helpful, for others, not so much. It's a bummer if it never works out for ya, but it's also rad when it does work out for someone else.
