The box gives you 20 corsairs, 20 Dark Elf Warriors with swords/spears or repeating crossbows, the new cold one chariot, 5 cold one knights, and a corsair lord that could be decent with some work. As well as a couple of spare beast masters from the chariot. Individual retail cost of the lot would be $212, so quite a savings when buying this way. Whether or not this helps you build an army is a different question, as even two of these boxes at a discount would be at least $260 and the army would lack any light cavalry, monsters, or magical support.
