AAAAaaaaargh!!!

If you happen to be "of a certain age", you'll have been brought up firmly believing that it's usually cheaper, per unit weight, to buy in bulk. A 2lb bag/jar/tin of WOTEVER has tended, most of my life, to be cheaper than 2 X 1lb tins bought separately.

Of late, I've been forced to amend my view of things. This stuff, if bought by the kg, would be 53P per kg cheaper if bought as 2 lots of eight than as one lot of 16.

Sneaky buggers!
