re: #55 Wendell Zurkowitz ((slave to the waffle light))
Germany had that set in law for a long time, namely that a list price could only be discounted under certain special circumstances (during the semi-annual winter summer clearance sales, for example)
I don’t know if a similar law exists here, but I’ll have to ask a couple of my students next week - they both work in retail management, so they’d be likely to know.
