Update:
I might have to take all my comments back. I have just received an email to say the items have been dispatched . The last email from them at 6:20 last night said they were all on back order. What the email actually said was:
"One of our aims is to provide a convenient and efficient service; in this case, we have fallen short.
Please accept our sincere apologies.
We'll send you a confirmation e-mail when your items are dispatched to confirm the date, contents and method of delivery.
