This has to be the coolest lunchbox I have ever seen. It is easily found elsewhere for £8.99 to be honest, but it is the 3 for £20 that make this a great buy and a fantastic gift if your struggling for kids or 'adult men' !!
If you take up the 3 for 2, works out at £6.67 each.
Quidco offer 6.6% cash back on this item too, so that's another potential approx. £1.32 discount off a £20 spend.
