Instead, shop smart and get it on one of these deals, which are the best around at the moment.

It's a 24 month contract so overall it will cost you £911.76.
Alternatively you can get it in blue with 1GB of 4G data, 1000 minutes, unlimited texts and a one year membership to the Gourmet Society for £29.99 per month. Overall that will cost you £719.76. As you only get a quarter of the data though it's probably not as good a deal.
With Vodafone you can get the gold version of the Samsung Galaxy S5 with 1GB of data, unlimited minutes and unlimited texts for £33 per month, with no upfront cost. In all that comes to £792.
It's also eligible for £48 cashback, bringing the price down to £744. Data may be pretty limited, but it's also quite cheap.
Or you can get it in white with 2GB of data, unlimited minutes and unlimited texts for £38 per month with no upfront cost. That's £912 overall but then you get twice as much data as on the previous deal, plus this one is eligible for £96 cashback, bringing the price down to £816.
Don't fancy committing to two years? Then get the Galaxy S5 in white, blue or black on a 12 month deal for £47 per month with a cost of £109.99 upfront. That will give you allowances of 1GB of data and unlimited minutes and texts and come out at £673.99.
That amounts to £792 over 24 months, making it identical to the first Vodafone deal, except without the cashback.
For a little more data you could always opt to pay £38 per month and get 5GB along with unlimited texts and minutes, though there is an upfront cost of £29.99. That amounts to £941.99 in total. Oh, and that's for the black version of the Galaxy S5.
Here's a deal for data fiends. You can get the black Galaxy S5 on Three with unlimited 4G data, unlimited texts and 600 minutes for £41 per month and no upfront charge.
In total that comes out at £984 over 24 months, which puts it on the pricey side, especially given that it doesn't include a huge amount of minutes, but if you use a lot of data then not having to worry about limits should make it well worth the asking price.
The good news is that this deal comes with £15 cashback, taking the total cost down to £969.
Alternatively you can get the S5 in black with unlimited everything for £43 per month. There's no upfront cost and no cashback so that's £1032 over 24 months, which might sound like a lot but it's a small price to pay for no limits on anything.
For that you'll get unlimited texts, unlimited internet and 500 minutes, though bear in mind that as this is T-Mobile you'll only get 3G data. Over 24 months the handset comes to £911.76.
If you'd rather have a lower monthly charge you can get it in blue with the same allowances and a monthly cost of just £27.99. However you'll have to pay £89.99 up front. It still saves you money over the life of the contract though, coming out at £761.75.
As that amounts to £911.76 overall it's hard to recommend as other networks have it either cheaper or with more and faster data.
With Tesco Mobile you can get the Samsung Galaxy S5 in black for £38.50 per month and that includes 3000 minutes, 5000 texts and 3GB of 4G data. There's no cost for the handset, so over 24 months that amounts to £924.
Alternatively you can get it in black or white with 1500 minutes, 5000 texts and 1GB of 4G data for £34.50 per month with no upfront cost. Over the life of the contract that comes out at £828, so you can save yourself £96 over the above deal but you'll have to get by on a third of the data and half the minutes.
Virgin Mobile also has a competitive deal, where you can get the Galaxy S5 in blue with unlimited minutes, unlimited texts and 2GB of data for £47 per month. However there is a £99 upfront cost so over 24 months it will cost you £1,227.
That's on the pricey side, but if you're a Virgin Broadband, TV or home phone customer you can get the same tariff for £37 per month, bringing it down to £987.
