I assume the best way to do it is to get a quote or two through places like gocompare and moneysupermarket etc but using false name/address and entering car manually (anything else I should do?). Then clearing cookies (using ccleaner, is that the best?), then doing a fresh new quote through a cashback site and buying there and then.
Is this the correct way or have I missed anything? Looking at £75 for Norwich Union, would be gutted to miss out!
Does the same apply to gas/electricity? Clear cookies after using uswitch is all that's neccessary I guess?
EDIT: I realise this doesn't guarentee payment, but it should give the best chance I think.
