For me it is when companies/services market themselves as donating to XYZ cause if I buy their product. If they want to donate, they should have already done that with the money they have. Asking me to give them profit so that they can donate is so obviously pretentious.
Generally yes. If I don’t need it, I don’t need it for free either. The price doesn’t change how much I don’t need a product.
Only made sense when some supermarkets had samples of hams and cheeses in those sections before COVID. Helped decide which one to buy.
