• Nine-roll pack
• 155 sheets per roll, 235 on mega rolls

We've found the nine-pack of this toilet roll close to its lowest price in the past six months. Standard rolls are also available in packs of four, 16, 24 and 36.

If you want larger rolls, Andrex also offers mega rolls in six-packs, nine-packs and 24-packs.

Zanussi ZEDB7002 Electric Blanket

Average price in the last six months: £55
Cheapest price in the past six months: £40*

• Dual controls
• Available in single, double, king and super king sizes

We like: It has nine temperature settings

We don't like: The skirt might be a bit fiddly to attach to the mattress

This Zanussi electric blanket has a longer-than-average power cord and a timer, which can be set up to nine hours.

It forgoes the usual four elastic strap corners for a fitted skirt which goes all the way around the mattress, designed to keep it firmly in place all night.

Cheapest price in the past six months: £3.50*

• 75ml tube
• Mint flavour

We like: The texture is nice

We don't like: It doesn't foam as much as some

This whitening toothpaste from Pearl Drops is currently the cheapest we've seen it in the past six months.

The formula combines low-abrasive cleaning agents with a natural mineral called Perlite, making it safe for everyday use.

Black+Decker 63099 Three Tier Heated Clothes Airer

• 140 x 73 x 68cm (10cm) HxWxD (D folded) 
• Weighs 5.5kg
• 300W

We like: The large capacity

We don't like: Could be tricky to fold away

This Black+Decker heated clothes airer has a hefty maximum load weight of 15kg and a power cord of more than 1.5 metres. It offers enough drying space to fit 24 medium T-shirts.

It takes up about the same space as a typical coffee table, and the shelves have to be folded away in a certain order when you take it down.

Philips Sonicare 5300 electric toothbrush

Average price in the past six months: £96
Cheapest price in the past six months: £55*

• Oscillating right and left
• 11-hour battery charge time
• Travel case

We like: Easy to use

We don't like: No battery level indicator

The 5300, part of the Philips Sonicare 5000 Series, comes with a W2 Optimal White brush head, but there are a range of toothbrush heads it can be replaced with. It has one cleaning mode and you can choose between low or high.

It also features a two-minute timer, battery level indicator and pressure sensor to tell you when you're pushing down too hard.

Nintendo Switch 2 + Mario Kart World

Average price in the past six months: £429.99
Cheapest price in the past six months: £404.95*

• 1080p screen
• Joy-Con 2 controllers
• Includes game download of Mario Kart World

We like: Better specs

Watch out for: Still pricey in a bundle

The Switch 2 launched a few months ago, so our hopes for any deals are quite low. Most bundle deals available right now won't actually save you much money on the new console either – except this one.

This deal comes with the highly anticipated Mario Kart World, and you'd be saving £41 compared to buying each separately.

Philips PureProtect 3200 AC3220/10 Air Purifier

Average price in the past six months: £244.08
Cheapest price in the past six months: £189.99*

• 51.5 x 27.5 x 28cm (HxWxD)
• Weighs 6.32kg
• HEPA and carbon filters

We like: Machine controls and app are easy to use

PlayStation 5 Slim (Digital)

Average price in the past six months: £399.79
Cheapest Price in the past six months: £280*

• Plays digital games only
• 8K gaming compatibility 
• Custom SSD

We like: Includes controller

Watch out for: Need to buy a separate disc drive if you want to play physical games

While it's cheaper than the regular PS5 Slim, this digital-only version of the console can't play physical games. Other than that, the hardware of this PS5 is the same as a standard model.

That said, if you want to add a disc drive at a later date, you can buy one separately for an added cost: SQUIRREL_TEXT_50010999 

This is the best deal on a PS5 currently, with price tags hitting new lows at £280 from EE.

Shark IP3251UKT Cordless Vacuum Cleaner

Average price in the past six months: £397
Cheapest price in the past six months: £314*

• Bagless and cordless stick vacuum cleaner
• 0.6-litre dust capacity
• Weighs 3.8kg

We like: Use on stairs and high places

We don't like: Smaller capacity than others

This cordless vac has a hinged stick to help reach under low furniture. The anti-hair wrap roller is designed not to get tangled up with long strands of hair, plus the handy motorised floor head detects the type of flooring it’s on and adjusts the suction power accordingly (so the manufacturer claims). 

It can be transformed into a handheld cleaner for tackling tricky areas such as stairs, upholstery and car interiors, and supplied accessories include a gap tool and upholstery nozzle. 

It weighs 3.8kg, so it’s not too heavy, and has a 0.6-litre dust capacity, which isn't as generous as some.

Is this vacuum as good at dealing with hair as Shark claims? Find out in our full Shark IP3251UKT review or see more of the best vacuum cleaner deals.

Dimplex 2.0kW Rapid Eco Oil Free Radiator

Average price in the past six months: £109.02
Cheapest price in the past six months: £82.44*

• Oil-filled radiator
• 65 x 57.5 x 17cm (HxWxD)
• 10.2kg

We like: Doesn’t topple over easily

We don't like: Not easily lifted

This radiator comes with three heat settings, a 180cm cable and a clear digital display, plus wheels that make it easier to move around the room.

You can set a 24-hour timer to suit your routine, and the integrated cable storage helps keep things tidy when it’s not in use. Safety features include automatic shut-off if the heater tips over, plus built-in overheating protection.

Take a look at our Dimplex 2.0kW Rapid Eco Oil Free Radiator review to find out if it will keep you toasty this winter, or see more of the best deals for people who are always cold. 

Eufy Clean X8 Pro with Self-Empty Station

Average price in the past six months: £456.11

Cheapest price in the past six months: £293.55*

• Robot vacuum cleaner
• 2.5-litre dust capacity

We like: App-controlled cleaning

We don't like: Big charging station

Eufy specialises in home security systems and robot vacuum cleaners, with the X8 Pro one of its more affordable vacs. In addition to the vacuum cleaning, it also has a mop function.

It can dock at its self-emptying station without user intervention, and it cleans the roller brushes each time it does so. You can adjust the frequency of emptying into the charging station via the app if you don't want this after every clean.

LG 43NANO80A6B TV

Average price in the past six months: £363
Cheapest price in the past six months: £289*

• 43-inch 4K TV
• LCD display
• Supports HDR10 and HLG formats

We like: LG’s operating system and remote work well together

We don't like: Not suited to big living rooms

This entry-level TV from LG incorporates the brand's Nanocell tech, which is designed to boost colour – that's unusual for a television that you can buy for less than £400.

For this price, you shouldn't expect a whole host of bells and whistles (gaming features are a little limited, for example). But there's still the option to use voice controls through LG's excellent Magic Remote, and recording is available, too.

Braun Series 9 Pro+ (96 generation)

Average price in the past six months: £351
Cheapest price in the past six months: £180*

• Foil
• Charging stand
• Travel case

We like: It comes with cleaning brush

We don't like: Expensive

We tested the 9610s model, but any Series 9 Pro+ product with a model code starting with 96 contains this shaver – it just has different accessories.

The model we tested here comes with a few accessories, including a pop-up precision trimmer, as well as a two-year guarantee.

Take a look at its score and compare it to other shavers in the Braun Series 9 Pro+ (96 generation) review, or see the best beauty deals.

INIU Power Bank

Average price in the past six months: £24.36
Cheapest price in the past six months: £22*

• 20,000mAh capacity
• 2.7 x 7 x 13.5cm (HxWxL)
• 342g

We like: LED screen

We don't like: We've tested alternatives that are quicker to charge

If you need a big battery to get you through long journeys, consider adding this power bank to your shortlist.

A handy LED display shows the remaining capacity from 0% to 100% in 1% increments, giving you a precise idea of when it needs a recharge. It includes USB-C input and output, along with two USB-A outputs.
