I have the promotional set that came out with the Classic NES gameboy series a while back. Came with some T shirts, Lanyards and odfest of all Scratch 'n Sniff "NES Classic Series" Stickers. SMB Smells like Spaghetti, DK Bananas, etc.
All packaged in a cardboard box resembling an NES. Spiffy.
Oh, and a few of those big plasic "Wall Stickers" that Nintendo sent out to Gamestop stores.
Ah, the single upside to working at Babbage's.
