The bestselling Ninja Thirsti insulated bottle has reached its lowest ever price thanks to a triple deal stack, with shoppers able to secure the 530ml version for just £4.49 — an 85% saving on its £30 RRP — by combining the current flash sale with a TopCashback new member bonus.
Flash Sale and Cashback Offer
With the bank holiday weekend approaching and forecasts predicting five days of scorching temperatures, Ninja has slashed prices on its multi-purpose bottle. The 530ml Travel Bottle, originally £30, is now on sale for £24.99. New TopCashback members who sign up for free receive a £15 bonus on their first qualifying purchase, plus standard cashback. After applying these, the bottle costs just £12.87 including £3.50 postage — a 57% total saving. Existing members can still reduce the price to £27.87 after standard cashback.
The larger 700ml Travel Bottle, down from £34.99 to £29.99, drops to £17.74 for new members after the bonus and cashback, a 49% saving. Existing members can get it for £32.74.
Features and Colours
Launched in 2024, the Ninja Thirsti has gained a loyal following, prompting the brand to expand its colour range to 11 shades, including classic black, white, grey, tropical blue, mint green, and lavender. The triple-layered insulation and leak-proof design rival premium brands like Stanley and Yeti. It is compatible with hot, cold, and fizzy drinks.
The bottle has over 500 five-star reviews. One customer said: "Love it! It looks amazing and keeps my tea warm for hours. Super easy to clean and no spills." Another noted: "My fizzy drink stays fizzy for about six hours." However, some users found hot drinks didn't stay warm as long as advertised. One tip shared: "Fill with boiling water for a few minutes before adding your drink to maintain temperature longer."
