Has it ? Because stock has sold out, doesn't necessarily follow that club have been conservative in their orders. Demand has presumably outpaced all projections. Unless you know the numbers. !
Well the facts are:
The club often runs out of kit a long time before the end of the season.
When shirts are available at the end of the season, they're not discounted - and haven't been so for many years.
Albion kit is not readily available outside of the official store(s).
This season's shortages have been cronic, with the away shirt selling out well before Christmas.
So, yes, it's an opinion but I would absolutely describe the policy as conservative. Availability does not match other clubs.
This season (possibly related to global issues) it's cost the club a shedload of potetial revenue. And, again, I think it's a shame discounted kit isn't available to the less well-off.
