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.
That happened years ago. Better search and more trustworthy sellers since products aren’t co-mingled. No way is some seller with years of positive reviews going to send you broken junk and not try to make it right.
