James White Veg It Classic Vegetable Juice 1L £2.30 @ Waitrose

Veg It is James White's bold tomato-based vegetable juice — carrot, beetroot, celery and a splash of sauerkraut for extra depth. No added sugar, one of your five-a-day per glass, and genuinely good chilled from the fridge. Waitrose has it at £2.30 instead of £3.45 right now, so a solid saving on a 1-litre carton that's handy for breakfasts, Bloody Marys or a quick nutrient boost.
