For those having trouble finding Beast Hunters DLX Prowl (being in the last wave, which seemed to have a limited release with the black redeco of Bumblebee - but scalpers and collectors scooped up Prowl)... there looks to be a second chance, with bonus 2-packs being found at American Walmarts, for just US$10 plus tax (which is less than half the price of two individual Deluxes in America).
Hopefully some of those filter through to the secondary market (if the Prowl wave never gets to Australia), or at least affects the scalper pricing of the Prowls already online.
