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.
Of course someone made a tool for this
It’s a good idea but it looks really outdated. Searched for 0.01 and the first page is almost entirely dead links or nowhere close to its listed price. Only 2 I found were the Baptist pamphlet for 25 cents and a washer for 36 cents(listed as 34).
So hopefully they update it for guys like OP
