20p a jar, for some good quality pickled onions is rather good value I feel, I was expecting to pay more just of the jar itself.
They weren't marked as reduced or anything, so I assume it's a nationwide deal (though I got this in Oxford).
I was looking for jars in Sainsbury's but ended up looking the cheapest item in a jar I could find. I eventually found these!
