There are three things a supporter can do to assist Carlton. If anyone can think of anything more let me know.
1) support Carlton's sponsors.
I think this is the most undervalued of the three. So far I have gone out of my way on numerous occasions to shop at Dan Murphys.
But it isn't enough to just shop there - we have to let them know why we go there instead of other bottle shops. It takes 5 minutes out of my day to write a letter to them (with a copy of the receipt) but it ensures they keep putting money into Carlton.
We are looking at Optus now for our phone bill. If they are similar in costing to what we are on - we will swap back to them.
2) membership
old one... but membership equals power. AFL takes us more seriously?

if we have over 30,000 members.
3) Buying Carlton product at Carlton.
There is a new video out on the best of Carlton's history. I haven't checked with the Carlton Shop yet, but I hope they are stocking it....
as this should be a big seller. Good quality vid. with highlights from
Braddles
Silvagni (dad and son)
Jeza
Nicholls
etc
etc
the best marks/goals over previous 40 years.
