As one who has yet to buy either a home or away shirt, club polo shirt on order, wouldn't it be better to offer a fiver discount on the new shirt to anyone who has bought a 'Gravesend Reporter' shirt whatever the colour.
Surely, that would keep all parties happy and at the same time increase the overall number of shirts sold. It's called the 'turnover' principle rather than profit per item. The Club are willing to try it with 'ladies day' tomorrow why not try it with the shirts?
Just a thought.
