btw, If you are trying to buy them both digitally in the U.S., The Crew is NOT on sale, the only thing I can find related to The Crew that IS on sale is a crew credits packs (which is in game currency). If you are out of the U.S. ignore what i just said. If it was actually on sale i might think about buying since I already own Driveclub and I like the idea of driving around the country.
edit: just noticed that you used "uni" earlier, so I'm guessing that you're not in the US. sorry
