One of the sure signs that you’re dealing with a materialist is that they brag about what a low price they paid for an item! Remember,in Islam the idea is a fair price not the lowest price possible(another modernist perversion which creates enormous suffering for certain producers).Also the sunnat is to give more than you are asked- either as buyer or seller.When I do that,mostly as buyer at the local farmer’s market,people are almost invariably in a state of shock.It’s as if they were saying to me”But that’s against our deepest beliefs about commerce.The lowest price is the law! Isn’t it?! “.No,that is the law of greed.I prefer the law of equity!
