I know that the pink PRS350 was available as a bundle in the US... now it's also available in Canada. Purchase a pink PRS350PC Reader and receive a bonus pink PRSASC35P premium cover case. Unfortunately you don't also get the two books that were available via the US offer... but you do get a keychain.
