An interesting one this, as I have deliberately avoided asking for the order reference and haven't tracked my order at all!
I know, it goes against the grain (even surprised myself!) but I know I would have been logging in several times a day just hoping it would change, even knowing it only updates on a Sunday!
I've booked my collection for 1st March so for me, it's not relevant (too much) when it actually arrives so my advice would be to only check it if you really want it ASAP!
