Where can i find this so called Purple TE Stick?

today someone told me at the arcade that he could trade his brand new still in box untouched TE stick for comic con or the purple TE stick and pay the difference (which would be a few dollars). i would like to know where and how i can do these if it’s true because my TE stick is still inside the box untouched and i would love to trade it for a purple one or comic con (highly unlikely since it’s very limited)

Purple one is Limited Edtion Femme Fatale TE stick. Violet buttons and balltop and bezel Mechanically Identical to TE.


You can still buy the Femme Fatale TE stick for the 360, but not the PS3
