Can you build some sort of creation right away?
Bust but maybe if I had the right pieces might have been able to make a 'Wares to Sale' station. - 5 points.
$4.99 / 52 = $0.10 per piece landing on the ratio for 0 points!
There is certainly some useful parts in the set for +5 points.
But this is certainly not the case for -5 points.
Total: B- set which seems right but some fun colors and perhaps some interesting pieces for cover building?
