Yeah, it's that time again.
So for those not familiar, Adbusters runs Buy Nothing Day every year the day after Thanksgiving (day after that for the international version).
So that'd be tomorrow for us Amurrricuns.
All you have to do to participate is buy nothing. As in, nothing. Don't spend money. That is all.
Consumatron covered Buy Nothing Day way better than I did. Go check it out.
