Best phone deals UK: Samsung Galaxy S6 deals
£60 off: The Samsung Galaxy S6 tops our smartphone chart as the best phone available to buy in the UK right now, but despite that it seems like sales haven't been as good as Samsung had hoped they would, which has let to a price drop to £499, £60 less than its £559 RRP. Strangely, when you look on Samsung's website, it still says £559 for the S6, but add it to your basket and you'll notice a “Special Offer” sticker that's lowered the price down to £499.

Free phone, £32.50 per month: If you'd prefer to get the Galaxy S6 on contract, Carphone Warehouse is currently offering a great deal that offers the phone for free with no upfront cost, and then it'll be £32.50 per month for 24 months. For that £32.50 you'll get an O2 contract that offers unlimited minutes and texts and 1GB of 4G data, which is a pretty great deal. Plus, if you buy through Carphone Warehouse you can pick the exclusive Blue colour option for the S6. Click here to view this deal.
Free phone, £31.99 per month: Another great deal on the S6 comes from Mobile Phones Direct, and offers the phone for free with an EE 24-month contract for £31.99 per month, and that gets you unlimited texts and minutes and 2GB of data. You also qualify for £20 cashback and free delivery, but there's no Blue option here. Click here to view this deal.
