I try to limit myself to no more than 5 open tins at a time, but while going through my terribly disorganized collection today, I spotted 2 tins of H&H Classic Burley Kake dated June 2011 and I'm just dying to pop one open. I know, rules are made to be broken, but if I slip over the edge on this one I'm afraid it won't end with just that one tin. So, tell me, how many tins do you normally have open at any given time?
