So, sod it, I waited until I had the money in Ireland, then had a bankers' draft written. The official order was then dated 22nd August (Friday), the money got to the manufacturers on the following Monday.
So, people, remember, what Apple means by 4 days is what everyone else means by 4 weeks. Clearly they’ve been inspired by the concept of days used by banks, when they’ve making excuses for denying you access to your own money*.
My only hope is that the Apple announcement of new products on 9th September (I'm writing this on the 7th) means there's a better product being announced, and the laptop was delayed so I'd be getting something better I actually ordered. I guess that's actually rather like hoping for a week of sunshine in Ireland.
*It always annoyed me that British banks used to claim that a cheque took three days to clear, a process that always, without exception, took at least four days. Their brazen abuse of both language and numbers always astounded me. Don’t they care they’re seen as arrogant? I guess not.
