Same here, the delays have been going on for about a year now, and I have found myself having to order from elsewhere, just to get the stuff in time for the job.
I agree with the above comments, the customer service is great, the order process is fine, but Scan seems to be let down by the rather annoying problem of having an estimated delivery date that quite often changes after the order is placed, then there is the problem that the money has been taken from your debit/credit card, and as such, it would take 5 days (ish) to get a refund to buy elsewhere so, cancelling is out of the question as a lot of people dont have money to buy from two places at once.
If I was to offer some constuctive criticism, I would suggest that whoever is in charge of Scan, steps back and looks at things from a customer's point of view and see how inconvenient this method of doing things really can be.
Sort out that warehouse problem/stock problem once and for all, and when that is sorted, you will have it all - Good customer service, a good range of stock and accurate delivery times.
Currently, you only have two out of three, and that third one is important to a lot of us
