Thanks to a bad print from K-mart i got Best Buy to price match. Now to go to wal-mart and "return" my gifts for Guitar Hero III. The misprint is on Page ten of this weeks K-mart flyer... check this link, it shows Spider 1 and two for 6.99 and a pic of 3 on Blu-ray with no attached price...therefore, also 6.99.
