May not be doritos but most supermarkets do their own brand and do salted, which I find are just as good as doritos. Depending what you want them for, if I'm melting some cheese over them and having with jalepenos and refried beans, the supermarket "budget" version seem to do just as well.
Just noticed this morning in Morrison's, they have Discovery banana peppers in a jar, as well as the sliced jalepeno.
