This is what the Albion wanted to avoid. Single season shirts slashed in price before end of January...
(Situation could be avoided by making them two seasons, I know)
In fairness... when new stock arrived in December, the club announced there would be no more coming. That was effectively last chance to buy.
I imagine sales would naturally fall sharply after Xmas when a kit is in its final few months. Think I saw WBA advertising 30/40% off shirts?
