I don't wish to be rude, but £1m is probably worth a lot more to you than it is to them.
They can probably find other ways to make that kind of money without changing their business plan or jeopardising their image.
Having said that, I still think there is a chance that they could enter the house - either as HMs or as guests, and this could all be a ruse to throw us all off the scent.
