As usual you can pre-order the iPhone 6S Plus from Apple's online store. You might not get such a tempting offer here, but it could be your best bet if you want to be one of the first to get your hands on the brand-new device.
The iPhone 6S Plus launches at the same price as the 6 Plus did last year, so for the 16GB variant you'll be splashing out £619, with the 64GB version costing £699 and the 128GB version weighing in at £789.
If you pre-order now though you're unlikely to get your purchase on the iPhone 6S Plus release date of September 25, with a 3-4 week dispatch time now assigned to all colours and storage variants.
EE has the iPhone 6S Plus up for pre-order, and you can get it on contracts with Wi-Fi Calling and 4G+ thrown in as well.
As you can imagine, the iPhone 6S Plus is pretty costly on contract too. EE recommends its £54.99 per month tariff with unlimited calls and texts and 10GB of data. You'll have to stump up £69.99 up front for the 16GB model however.
That increases to £149.99 for the 64GB model, and £249.99 if you fancy 128GB of internal storage (but the latter does come with 20GB of data).
Vodafone also has its pre-order page open for the iPhone 6S Plus, although it's saying it expects the handset to now ship from October 2.
The highlighted deal here requires £69 up front for the 16GB model, and then £49 per month in return for unlimited calls and texts and 2GB of data.
Jump to the 64GB model and you're looking at £99 up front and £54 per month for unlimited calls and texts, plus a more generous 6GB of data.
O2 will be stocking the iPhone 6S Plus, and you can now pre-order from the official O2 website.
Up-front costs start at just £9.99, but you'll have to settle for the 16GB iPhone 6S Plus and either a high monthly cost or very little data.
You could pay just £9.99 up front and get a whopping 30GB of data plus unlimited calls and texts, but you'll have to part with £64 every month for two years.
O2 is also offering a similar upgrade policy to the one Apple has just introduced. Known as the O2 Refresh 30GB tariff, after 12 months you'll be able to upgrade to the latest iPhone without a buyout charge; you just need to trade in your iPhone 6S Plus, and O2 will also pay off your remaining device plan.
Those of you on Three won't miss out on the iPhone 6S Plus action, with pre-orders up and running here.
Three is the home of all-you-can-eat data, and you'll be able to take advantage of this with its iPhone 6S Plus tariffs. £99 up front, with a £56 per month outlay will get you a 16GB iPhone 6S Plus and unlimited everything.
You'll also be able to phone, text and use data in 18 countries (including the USA, France, Italy, Spain and Australia) without any roaming charges.
If you like a wide choice of tariffs in one place then head over to Carphone Warehouse's iPhone 6 Plus pre-order page, where you'll be able to see contracts from EE, Vodafone, O2 and the retailer's own network, iD.
You can snag yourself a free 16GB iPhone 6S Plus, but you'll be shelling out at least £64 per month for the privilege, so we'd recommend parting with around £100 up front to keep things a little more tame.
Fancy picking up the new iPhone 6S Plus during your weekly grocery shop? Well great news, as you'll be able to get the new iPhone from Tesco. You can even pre-register your interest right now.
Tesco has killed all upfront costs for the 16GB, 64GB and 128GB models of the iPhone 6S Plus, but that means monthly costs (start at £46, rise to £61) are higher and there's no sign of unlimited texts or calls (5000 a piece across the board) anywhere.
Virgin Media will be offering the iPhone 6S Plus to its customers, and while it has pre-orders open for the iPhone 6S, it's yet to release tariffs or sales information for its bigger brother.
Currys PC World
With the Currys and PC World stores owned by the same company as Carphone Warehouse, it's little surprise that these shops will also be stocking the iPhone 6S Plus, although no prices have been announced so far.
