I love crisps, they're one of my biggest weaknesses and I eat them far to often.
There aren't many flavours that I don't love but some of my more favoured ones are Worcester sauce French Fries, cheese Quavers, Walkers salt & vinegar and prawn cocktail, Walkers Max paprika, Sensations Thai sweet chilli, Doritos cool original and chilli heatwave, Monster Munch pickled onion, cheese Wotsits, Skips prawn cocktail, sea salt & balsamic vinegar Kettle Chips, Pringles salt & vinegar and sour cream & onion.
I also used to love the Walkers Marmite crisps but they were discontinued a few years ago.
I recently bought a tube of dill pickle flavour Pringles that had been imported from America and they were amazing! I really wish we had them over here.
