Drop Amazon a line or phone them asking where it is? The worst that could happen is that they give you a £5 gift token for any inconvenience caused.
Stress than you are a Prime customer and were expecting delivery today.
Normally (and you mileage may vary) whenever I get a Saturday despatch from Amazon for a Monday release like clockwork on a Sunday I get a "there has been a delay in transit for your delivery" and it then is delivered on Monday. Never has one of these made it to me on a Sunday.
Spoke to Amazon CS - they told me it would arrive 26th, I gave some stink and then got a push notification on my phone that it just got dispatched and will arrive tomorrow very weird ¯\(ツ)/¯
No payment taken from Zavvi yet for the steelbook. Has anyone had the steelbook sent yet? I ordered this the day it was put up for sale.
Amazon are now out of stock with a delivery date of 31st August. Zavvi still have not sent my steelbook which was ordered on 30th April. I doubt I will see this anytime soon now. The one disc I wanted for years and they muck it up for me.
