The BB pickup $1 off works this way :

When you check out, it defaults to store pickup. Instead pick the shipping option.

Then you'll see besides the store pickup option a green $1 OFF.

Go back and choose pickup at store and you get a buck off.

To some people like me, saving a buck goes a long way especially when it comes to video games which are only for entertainment value and not feeding or putting clothes on real human beings.
