I can just remember (as a child, of course!!) UK Woolworths in the 1930s. They still had "3d and 6d Stores" above the shops and were still struggling to maintain that promise. For example, a table lamp might have been 6d for the base, 6d for the lampholder and 6d for the shade. If, as I understand, they were really selling Clariss Cliff (sp?) then each piece must have been 6d (or less!). For the children among you, that of course was 2 1/2pence.
