No, that is fine, I was not as clear as I might have been.
One needs to consider why there is a shortage
is it:
a) deliberate by GW to create "hype" and "buzz" around a product, (this also feeds exclusivity and may increase future sales as they might sell out quickly)
or,
b) a genuine miscalculation by GW
Given that the second resorts in a drop or delayed sales, whereas the first promotes it be that it was planned all along. Which kinda sucks for us as a consumer, but you know these things happen.
