Shoppers snag £30 Ninja leakproof travel mug for less than £4 in Boxing Day sale

Ninja has become one of the first brands to kick off their Boxing Day sales for 2024, slashing prices on everything from air fryers to knife blocks. Many of the discounts on the site are either cheaper than Black Friday, like this deal on the Ninja kettle which takes it to its lowest ever price, or include freebies and bonus items with purchases.

However, shoppers keen to snag one of Ninja's newest bestsellers have found a way to stack deals and get it for a fraction of even the sale price. The Ninja Sip Perfect Travel Mug only launched in the UK this month but already has a devoted following among coffee and tea drinkers, with many dubbing it the 'perfect' insulated cup.

The mug comes in a trio of stylish colours with options in black, white and green. It launched costing £29.99 and the Boxing Day sale sees it reduced by a third to £19.99, a chunky saving for anyone looking to snag the game-changing gadget.

However, savvy shoppers have spotted a way to bag it for even less thanks to a money saving site. Bargain hunters who sign up with TopCashback in time for the Boxing Day sales can get the mug for £3.66 by signing up as a new member, claiming a free £15 signup bonus and cashback and then clicking through to buy the travel mug.

As you'd expect from the innovative brand, which has transformed UK homes with gadgets bringing new technology to everything from air fryers to barbecues, this is not a bog-standard travel mug. It locks shut making it totally leak-proof but also has a specially invented HeatStore technology that cools drinks down to the perfect sipping temperature in minutes but then holds it there for hours.

• Despite only being on sale for a few weeks, the Sip Perfect has an average rating of 4.7 out of 5 stars on Ninja's website with shoppers praising its quality and value for money. One happy customer described it as 'top class' although also flagged it was a bit heavy, adding: "I had high expectations of this product as Ninja has a reputation for quality and I’m pleased to say it didn’t disappoint. As an outreach worker a good thermal cup is an important part of my “kit” I decided to use this mug for a few days before writing the review to make sure I had put it through its paces. It looks great and has the quality finish you expect from Ninja. It didn’t leak even when in the bottom of my bag. I followed the instructions about preheating the cup and I think my filter coffee was hotter than when I poured it from the pot. It stayed hot for several hours which is brilliant when you are away from access to drink making facilities. I used the cup while working from home and again it kept my drink hot for hours.

  "It’s easy to clean, looks great and has a tough external shell. It fitted nicely into the cup holder on my car. The only slightly negative thing I would have to say about this cup is, it’s a bit heavy but worth dealing with that as the product is a good one. I’m very impressed."

  Another shopper described it as 'great for mums on the go,' adding: This is perfect. As a new mum with a newborn baby I use this to keep my tea, hot chocolate and cappuccino nice and hot. I take this out with me whilst travelling and I love it! The only thing I would suggest is that they could add handles to the cup as well."

  Another praised it for being dishwasher safe: "The cup is stylish and keeps drinks hot for quite a number of hours. It washes well both in the dishwasher and by hand and it is easy to separate the different parts. The cup doesn’t fit in my car’s central cup holders but fits in the door. The cup doesn’t leak but I would have preferred a lid that closes automatically once you stop pressing on it because I have forgotten to close it a few times, this is user error."

  However, not everyone is converted despite the most negative review on the site still being three stars. The critic compared the mug unfavourably to another Ninja product, saying: "Doesnt keep drinks hot for long. I have the flask and that keeps hot drinks hot all day so I thought the travel mug would be the same. I should have just stuck to the flask. Not worth buying."

  For coffee fans the perfect travel mug is a bit of a Holy Grail. If this deal - which takes the cost of the Ninja mug to cheaper than many takeaway lattes - doesn't appeal there are plenty of other great options also discounted in various winter sales.

  Coffee fans keen to pick up an alternative premium mug can snag a huge 26% off the Contigo Luxe on Amazon at the moment. Normally it's £39, but it's been reduced down to £28.99. Also on Amazon, Dualit has a stunning brushed stainless steel option currently reduced to £19.99.

  Stanley's iconic Aerolight is the hot drink version of the Quencher and comes in slightly cheaper than the celeb-loved cold drink cup. It's available in eleven colours with prices from £33 on the Stanley website, but if you're happy to choose specific colours you can get one from £30.

  Ninja is not the only retailer that has pushed the button on the Boxing Day sales early this year. Boots, Dyson, Shark, Debenhams, Oodie, Ugg, Monica Vinader and Roman all have sales live already, many with discounts equalling or better than the November sales.
