FYI, if you are talking about the G2 Jazz that came with the Optimus Prime and Legends Motermaster & Thundercracker it was an online exclusive at HTS.com, TRU.com and BBTS.com not Walmart.
I have one that I'm selling on eBay right now. Ends tonight at around 10:30 EST. US buyers only. Here's the link: Transformers Generations 2012 G2 JAZZ Ultimate Gift Set Exclusive Loose Complete
It's even cheaper now. Still on sale at tru.com for $19.99 Tranformers Generations Ultimate Gift Set - Hasbro - Toys "R" Us
