Amazon gives non-Prime members free shipping at $35 or more of eligible items. Instead of simply letting users get the product with free shipping, they’ve added a discount that prices it exactly one cent below the $35 limit, while only subsidizing the price with $3.38, which is about half of what they’ll then charge you for shipping.
(In the Netherlands) Non profits are allowed to make profit, they just need to pay tax above a certain amount of net profit. The thing that makes them “non-profit” is that they are prohibited to pay out that profit. Hence there is no incentive for (excessive) profit.
It’s like that pretty much everywhere including the USA. People just don’t understand.
