My local Boots at Trafford Retail Park had a range of trimmers and groomers on clearance.
I chose two.
The Super Groomer had a ticket price of £20 but scanned as £13.33 on the till. I've had a quick look online and this retails at £50 and above.
The Super Stubble had ticket price of £15 but this scanned as £9.99 at the till. Again retails as much more.
I also had £5 off £20 spend on the Boots app which came in handy.
