"The Giantslayer Pawn Collection, together with the creatures from the Pathfinder Pawns: Bestiary Box collections, provides pawns for nearly every Giantslayer encounter."
This is slightly false advertising... By buying this product and the pathfinder bestiary box(es) you will still end up with not enough Frost and Fire giants. As mentioned by Marco Massoudi, you definitely need the Out-of-print-yet-requested-by-many "Monster Codex Box" to get all the giants you need to run this adventure.
