Thinking about it, it must be a legal requirement to provide a breakdown like that?
Imagine if that approach happened elsewhere - so your new iPhone costs £500. Ace! Oh, but wait, there’s our marketing supplement of £300, plus our gullibility fee of £200, (or £250 if you buy the limited edition in brown) so actually what you thought was £500 is actually £1000. People calling Apple cunts because they charge a £200 gullibility fee “I’m happy to pay a £100 gullibility fee but £200 is taking us for mugs”.
