You need to spend £100 in a single transaction (ie one shopping cart) but you don’t need to spend it all in one department. Once your shopping is done, simply apply the code GOOGLETESTJUNE1 at the checkout. You can only use the code once per transaction. To find out more about the Google nest Mini, you can read our review but – spoilers – we think it’s a five-star piece of kit. You can check the John Lewis product info here. That, however, is far from the end of the good news. John Lewis has a sale on at the moment, so not only can you get the Nest Mini, but you can save money on other items as well while you’re at it. We’ve got some recommendations. If you’re after a new vacuum cleaner, the Dyson Cyclone V10 Absolute is available for £399, a saving of £50. The V10 is still one of the best cordless vacuum cleaners around and right now it’s the best value Dyson you can buy. When we reviewed it, we gave it 4.5 stars out of 5. This particular model is in blingin’ gold as well.

If you happen to be in the market for a food, processor, the Bosch MCM3501MGB is a solid choice. You can get it for £94.99. That’s not a sale price, by the way, but it is the best price currently available. It’s powerful and a really great all-rounder, with all the accessories and attachments you could want in a food processor. That includes a jug, so you won’t need to buy a separate blender. 

There are also some good deals on microwaves. You can get £10 off the Samsung MS23K3555EK microwave in black, bringing the price down to £79. It’s an 800 watt microwave with a 23 litre capacity. It has automatic cooking programmes and a deodorising setting, which forces air from the appliance so that you can heat up an apple pie after cooking a curry and your dessert won’t come out smelling like lamb bhuna.

There are also great deals on washing machines, like the Samsung WW90J5456MA ecobubble, which is available for £379, down from £449. It’s A+++ energy-rated and can take a 9kg load.   John Lewis is also one of the retailers participating in LG’s £300 cashback deal, which is running until 14 July.
