Earlier quoted context omitted.
Do it enough and they'll stop. All of my Amazon order emails now only tell me the order number and the total cost, with zero information on what products are included.
I wonder if Amazon was worried about companies like Google mining sales data from emails? Or something along those lines
Capital One has a tool called "Paribus" that, if you connect your email, will monitor and get refunds if prices drop or the item doesn't arrive on time. They used to do it with Amazon; they'd tell you something didn't come in the Prime two day shipping window and give you a pre-prepared complaint to get a free month of Prime as compensation.
I can't imagine Amazon liked it much.
