I really should post more considering I read these uk threads like a hawk each year!
But for those comparing and obviously keeping notes LOL...
I'm in East London (Canary Wharf); ordered on the App - hammered away from 8am till the page finally loaded, and ordered smoothly via my Pre-Favorited choice of 7 Plus 256GB Matte Black.
Confirmation email was received as an 8:05 order confirmed 6-8 business days 27/29 Sep standard shipping.
At 18:25 Friday evening I noticed I was already bumped up to 20/22nd September.
Obviously I'm checking the app just as much as you lot hehe, and while I don't want to be too greedy, there has been no sign of further bump-age since. I'll be sure to let you know if there is!
As a side note, immediately after my phone order I put a separate silicone case order in too, while slated for a 15th to 19th Sep delivery, it remains sat on 'Processing' although I don't really care about that as passionately.
