Hi Bayar,
I don't work for MoneySupermarket but I'm a regular member here so I hope my input helps. I'm sure Richard Mason may reply in due course.
I think it's a good idea from a marketing point of view, but a bad point on the basis of cheap gimmickry. Another rival already has a similar prize winning offer in place whereby people go online to quote and they may be selected at random to receive the prize. They also promote that you don't even need to be at renewal date to get a quote. All it does is increase the quote bank to make them look better by offering quotes to more people.
In my view, this is just a cheap tactic to cheat figures. Of course, someone may be the lucky winner of £10k, £20k or whatever the prize may be... but you can imagine the high volume of quotes that are done just for the sake of winning the prize. It creates a lot more work for intermediaries trying to sift through the time wasters on the net and it won't make the business a great deal more money.
I don't think MoneySupermarket needs to rely on poor attempts to increase their quote bank when they are already one of the leading price comparison sites!
So... a good idea, or a bad idea... MoneySupermarket...?
Kind Regards,
Vicissitude
