Just see it as a way of helping the club financially when they (we) need it most.
I did win a small prize and donated it back. I would and will do the same whatever the prize until we are debt free. When we get to that point I would prefer the prize to be in club shares or at least to have that as an option.
On that topic I know the board are looking into this but if there was a simple way of buying shares in say £100 blocks I think the rest of the debt could be cleared very quickly.
