Too Useful to Get Rid Of

My Amazon shopping cart normally has 1-5 items.

Abandoned shopping carts are a burden to supermarkets that have to retrieve them. Abandoned carts are also a nuisance in the on-line world because they distort merchants' data on what products attract customers.

They also cause an administrative burden by triggering e-mail reminders to "customers"; if the messages bounce back, eventually the merchant has to intervene and delete the cart.

Which brings us to the mysterious shopper John Smith who has been abandoning carts across the Internet.

John Smith started shopping early on a recent Wednesday and didn’t stop for days.

He visited an auto-supply site where he loaded his cart with a replacement turn-signal lever, emergency strobe light and two dozen other items. He hopped over to a home-goods merchant for another 10 items including wood picture frames, address plaques, a towel rack and mailbox. He ordered one of every kind of baby bundle, ranging from about $80 to nearly $500, from a site that sells infant sleeping boxes popular in places such as Finland.

When the roughly 48-hour spree was over, John Smith did what he always does. He walked away without buying anything.

For more than a year, online merchants selling items ranging from kayaks to keychains have puzzled over the mystery shopper with the generic name behind thousands of abandoned carts.

In a triumph of investigative journalism the Wall Street Journal tracked down the serial looker. Merchants noted that John Smith always had a gmail address. Repeated telephone calls to Google unearthed the truth:

The mystery shopper is a bot of its own creation. The purpose: making sure the all-in price for the product, including tax and shipping, matches the listing on its Google Shopping platform or in advertisements. It wasn’t to cause angst to merchants due to thousands of abandoned carts.

Internet platforms and news sites have been flooded by bots that dispense fake news, sell products, and degrade debates. So why aren't they eliminated completely? Because the platforms find them useful, too.
