I ordered (from 2 Degrees online) a Pro Max 256Gb Space Grey on Saturday evening when the delivery date was still 'from 20 September'. I did not get the shipping confirmation and called 2 Degrees this morning to enquire about it. Got through to a very helpful agent who advised that as I had not received the shipping confirmation by now, it was most likely that I would have to wait 3-6 weeks for the backorder. I'll probably have made 2 payments on the payment plan by then.
It's disappointing that 2 Degrees systems were unable to advise this upfront, after all, they would have an idea of their initial order with their supplier. I noted yesterday that PB Tech had just 1 unit of some models in stock so low stock levels are not uncommon.
