Football Shirt Costs

In one of my less busy moments at work this morning I wondered aloud why the Albirex Niigata replica shirt costs 98 SGD was nearly twice as expensive as the Geylang United one which costs 50 SGD.
Koh Mui Tee, who is the Albirex Niigata manager, tells me that it is down to demand. They shift about 150 shirts a year while Geylang United manage a fraction of that.
