NutriBullet makes some of the best blenders around, and they're not cheap, so when you can pick one up for a 1/3 off, it's worth taking note. In fact, this one, part of the 600 series, is our favourite NutriBullet blender.
Argos has this brilliant five-piece blender for a smidge under £40. It features a 600W motor which spins its stainless steel blades as an incredible 20,000 RPM. That's fast enough to pulverise anything you care to blend and can be simply used to crush ice if that's what you need.
