When in doubt, small prizes (the items in Plinko/Cliffhangers/Secret X) are expensive anymore. Except for the TPIR 2010 games - $20/PC, $30/DS, $40/Wii.
Also it would pay to just simply pay attention to your surroundings. If you can (I've never been to the studio), listen to descriptions and look at stuff - especially in Now or Then...if it says NEW on the pack...
