Anyone spending large amounts of money would be best advised to use several phone as Channel 4 reserve the right to discount votes if they suspect fraudulent multiple voting.
Anyone who makes 200 calls for one hm will probably be cancelled out by an equally stupid voter for one of the other HMs.
The large numbers of individual voters will make the small number of £50 voters irrelevant, but no doubt Channel4 and Endemaol will thank you just the same.

I hope you are the boss because if you're not and he finds out, you're a goner.

There's gonna be MILLIONS of people voting tonight and contributors to this forum will probably count for about 1% of tonights voters. I imagine the vast majority of votes will be from people who will vote once or maybe twice and the voters who are spending £50 and upward will be in the minority and as someone has already said these types of voters will probably cancel each other out anyway. It's a complete waste of money spending upwards of £50 quid

that won't be happening on telewest because we have a proper return channel (read: not a telephone line) to return votes
