Hi Waffler - I did the same - nipped to my fave blackberry spot and picked a few, unfortunately left it for a couple of weeks, went back and they had all gone off! what is the old saying? something about after the 11th september the devil p****s on the blackberries and then they are no good? something like that anyway! And after I'd got a lot of jars from lakeland plastics as well!
