One lesson I learned long ago is that Amazon sometimes offers different pricing when I am logged-on versus when I am browsing anonymously, with the price always being lower with the latter. And if I place an item in my cart while logged-on, it sometimes declines in price the next day, but if I wait more than a day or two to purchase it, the price always rises back to the default or even higher.
Amazon has announced a new policy for sellers, with it taking effect July 1, where logons will require the use of a smartphone for two-step verification. Starting a few weeks ago, sellers were required to click on the "not now" button to avoid two-step verification.
Amazon patented advanced predatory behavior for use in actual retail stores, "Physical store online shopping control," preventing shoppers from comparing prices by monitoring online activity conducted over its wireless network and responding by displaying a different page, directing an Amazon employee to harangue the shopper, sending the customer a text message or email, or blocking Internet access to non-Amazon sites.
Hopefully we will see anti-capitalists establishing powerful wireless transmitters in nearby buildings, along with highly directional antennas, to give Amazon shoppers the opportunity to price-check outside of the oligarchy, though that would require shoppers to carry two wireless devices.
Amazon's tactics are very different than the ones used by stores offering frequent shopper cards. Prices are the same for all shoppers, with the retailer only discovering the identity of the shopper at checkout. And some of the cards do not require surrendering personal data, though not giving it will result in not receiving any coupons.
Only someone with more dollars than sense would shop in such a store.
