Members of the Extreme Couponing and Bargains UK Facebook group had their interest piqued following a post to the site.
The post said: “Ninja Speedi at a good price, I would say the same price on Argos and Ninja website, but only grey colour, plus 10 per cent off if you sign up for the newsletter on Ninja website and an apron free (worth £19.99).”
The advert on Amazon reads: “Ninja Speedi 10-in-1 Rapid Multi Cooker and Air Fryer, 5.7L, Meals for 4 in 15 Minutes, 10 Functions, Fry, Steam, Grill, Bake, Roast, Sear, Slow Cook & More.”
The gadget is available either in “sea salt grey” or “copper black”.
The online retail site is currently selling the product for just £149, a reduction of 40 per cent from the usual retail price of £249.
If you’re an Amazon Prime member, you get the delivery free.
John Lewis is also selling the sea salt grey model for the reduced price and also offering free delivery as the price is more than £50.
Replying to one comment, the original poster said: “If you go to their website [Ninja] and sign up for the newsletter, you will have another 10 per cent, so £135. Plus a free apron worth £19.99.”
Fans were keen to get their hands on one at that price.
One member of the Facebook group wrote: “Can’t wait for mine to be delivered today and try it!”
Another wrote: “I love mine, it’s brilliant!”
While on the Amazon site, one reviewer was suitably impressed, saying: “I recently acquired the Ninja Speedi 10-in-1 Rapid Cooker, and it’s proven to be a true kitchen companion for those who value efficiency without compromising on quality.
“The claim of preparing meals for four in just 15 minutes may seem ambitious, but the Ninja Speedi delivers on its promise.
“Whether you’re air frying, roasting, or sautéing, it consistently provides speedy and evenly cooked results.
“While it’s undeniably efficient, the 5L capacity might be a bit limiting for larger meals or families. However, the trade-off is its versatility.
“With 10 cooking functions, including air frying, slow cooking, and dehydrating, it caters to a wide range of culinary needs.
“Navigating its controls is a breeze, and clean-up is hassle-free with dishwasher-safe parts.”
The news comes after Ninja unveiled its latest kitchen gadget, the first vertical two-basket air fryer, which will go on sale later this year.
The Ninja DoubleStack air fryer will be available in two different sizes – either 7.6 litres or 9.5 litres.
Unfortunately, Shark Ninja has not yet released how much the device will cost when it becomes available for purchase in the UK.

Meanwhile, Tesco fans have been rushing out to get their hands on an air fryer which can fit a whole chicken, selling for just £47.
