And the reaction of pricing to supply and demand is hardly ever instant or without reactive elements. You saying that 5€ is ok for lights because supply/demand... riiiight, as the supplu and demand have been so well defined for an item that just released? And yea, actually housewives do write/talk to their stores about prices, and actually it matters. WEIRD!!!
I am not saying 5 is alright for the lights. I am saying that if YOU think it's too much don't buy it and if the rest of the people feel the same, the price will go down.
And no, the letters don't matter. If you will keep buying stuff you're whining about, letters won't change a thing.
