Just looked again at the Kooga site. Only three items left from their 2011 sale, it looks like everything else is gone.
This suggests that people are very keen to buy supporters gear but not very keen to pay $150+ for the pleasure. Surely there must be a law of diminishing returns, which suggests that if merchandise was more reasonably priced they would sell more and teams would still get the same total income. One of my pet gripes is going to watch the Tahs and seeing so little sky blue at the stadium. Perhaps an overall price reduction might have the effect of getting more people to buy and wear the gear to home matches.
