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.
It’s literally not even hard, but yes you have to put some effort into it, and of course it isn’t convenient. You’ll probably save money, though - Amazon hasn’t had the best prices on 95% of items for many years now.
If you aren’t OK with being slightly inconvenienced, you can always keep supporting Nazis 🤷♂️
“Not convenient”? Have you any idea what it’s like to live in the US rural south? It’s Walmart, Amazon, or just fucking die.
