Bunch of PlayStaion crossbuy titles on sale from the PSN store, so they're all digital copies. Buy the PS3 version, get the Vita version for free. First price listed is the currently on-sale price while the second price is for PS Plus members which is usually just an additional 10%-25% off. I'm not too sure if Ratchet & Clank is crossbuy though.
