During this exchange a few weeks ago, I said that I had received no invoices from Google. I have just discovered that this is not correct. Like you Nigel, I have been receiving an invoice every two months for ‘zero’. It’s just that they have been going to an old e-mail address which I no longer use, but is obviously still regarded as my current address by Google. Have now attended to the necessary admin, but thought i should mention it here to dispel any confusion that my previous remarks may have caused.
