They all go up and down in price, sometimes only for a few hours so its worth keeping an eye on it
The Geetas Lime and Chilli chutney has always been my favourite, a nice spicy kick to it. Their Mango chutney is really nice too, lots of whole spices, also there's no nasty additives in either.
I must try Pataks Chilli Pickle, have never tried one I really like.
