I logged into Overstock's customer service chat because it had been a few days, and some posted that you could get the discount immediately by talking to a rep. Well, I don't know about others, but my rep told me that I would have to wait at least the full five days before requesting activation. Coincidentally enough, the discount appeared later that night. I received a welcome e-mail to Overstock Auctions, I checked for the discount in my cart, and it was there.
