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.
No, those are Google products, Alphabet is Google’s parent company and also holds many other companies like Waze and Doubleclick.
Except the team behind Waze was merged with the one behind Google Maps, they just keep the two apps separated (for now) to prevent any backlash. Same with Doubleclick and Google Adds. (In fact, I’ve got the impression Doubleclick became nothing more than an alias for Google Adds. And for quite some time, I might add.)
