Hoover's free flights, 1992

Hoover's British business went into 1992 in poor shape. Its profits had roughly halved since 1987, the recession had cut demand for household appliances, Dyson was about to arrive with a better vacuum cleaner, and unsold stock was accumulating in warehouses. A small travel agency called JSI Travel, which was also struggling in the recession and needed to sell cheap seats, approached Hoover with a promotion: anyone who spent at least a hundred pounds on a Hoover product would receive two free return flights to a European destination. Hoover agreed, and through the autumn of 1992 the products sold well enough that the company decided to go further. In November it extended the offer to the United States. For the same hundred pounds of purchase, a customer could now claim two return flights to New York or Orlando, which had a retail value of around six hundred pounds.

Before extending the offer, Hoover put the plan to risk management professionals. One of them, Mark Kimber, said later that the promotion made no logical sense to him, and that after trying to calculate how it would actually work he declined to offer risk cover at all. Hoover went ahead regardless, relying on two assumptions about how customers would behave. The first was that most buyers would spend well above the hundred pound minimum, so that the extra margin would help pay for the flights. The second was that the claim process would discourage most people from finishing it. That process required a receipt posted within fourteen days of purchase, a registration form returned within another fourteen days, a travel voucher, three choices of airport and date that Hoover was entitled to reject, and three further choices that it was also entitled to reject before offering a combination of its own.

Neither assumption survived contact with the public. Customers bought the cheapest qualifying product they could find, very often the model priced at £119.99, and some did not bother to collect it from the shop. Then they filled in every form. Hoover had planned for around 50,000 applications. Contemporary accounts put the eventual number at somewhere between 200,000 and 300,000, which at two flights each meant as many as 600,000 seats. The arithmetic inside the company was stark: roughly thirty pounds of profit on a £119 vacuum cleaner set against at least six hundred pounds of flights, so a loss of around £570 on every customer who completed the process. The promotion generated about thirty million pounds in sales. The flights it had promised were conservatively valued at more than a hundred million.

Faced with those numbers, Hoover began to obstruct its own customers. Applications were rejected as incomplete. Departures were offered from airports hundreds of miles from where people lived. Forms were posted on Christmas Eve so that the postal shutdown would carry people past their fourteen day deadline. One Hoover executive told a travel agent that the intention was to dissuade people from travelling, because every completed trip cost the company money. Customers organised in response. Harry Cichy and Sandy Jack founded the Hoover Holiday Pressure Group, which grew to several thousand members, bought shares in Maytag, Hoover's American parent company, and sent representatives to its annual general meeting in Iowa. In June 1993 a man in Workington named Dave Dixon blocked a Hoover delivery van into his driveway with his horsebox and kept it there for thirteen days, until a court ordered him to release it. Legal action over the promotion continued until 1998.

Hoover dismissed the president of its UK division along with two senior marketing executives, set aside twenty million pounds for a flights fund, and reported a loss of £23.6 million on sales of £390 million for 1993. Maytag was eventually ordered to pay the equivalent of $72 million to fly around 220,000 customers, and a large number of applicants received nothing at all. The figure most often quoted for the total cost is £48 million. In 1995 Maytag sold Hoover's European business to the Italian manufacturer Candy, at a loss of $81 million against what it had paid for it six years earlier. Hoover's share of the British market, which had been around half for decades, collapsed, and the market was flooded with unused second-hand Hoovers that people had bought only for the flights. In 2004 a BBC documentary in the Trouble at the Top series told the story again to 1.7 million viewers, and Hoover's royal warrant was withdrawn afterwards.

Where the evidence stops. The events are well documented and the broad shape of the story is not disputed, but no primary Hoover or Maytag document is in the public record. What exists is contemporary newspaper reporting, trade press retrospectives, and the BBC documentary. The numbers differ between these accounts because they are counting different things: applications received, customers eventually flown, the face value of the flights, and what Maytag finally paid are four separate figures, and they are often quoted as if they were one. The £48 million figure is the most repeated and the least explained. Kimber's account of declining to underwrite the offer is his own recollection, given years afterwards. The story can be treated as settled. The individual figures should be treated as approximate.

The people who approved this promotion were not fools, and they had done a calculation. What they calculated was the cost of the promotion at the level of take-up they expected. What they never calculated was the cost if every customer who qualified came to collect, and that second number was the only one that mattered, because it was the one that could end the business.

Every offer has two costs. The first is what it costs when roughly the number of people you expect take it up, and every promotion is planned around that figure, because it is the figure that makes the plan work on paper. The second is what it costs if every eligible person redeems in full, and almost nobody works it out, because it feels like an absurd case that will never happen. Hoover's plan rested entirely on the first cost and on two stories about why the second would never arrive: customers would spend far more than the minimum, and customers would give up on the paperwork. Neither story had been tested against anything. They were hopes about behaviour, and the company staked its European business on them.

The practical habit this case teaches is simple to describe and rarely done. Before signing off any discount, referral bonus, free trial, cashback scheme or giveaway, work out what it would cost if every single eligible person took it, and then ask whether the business could pay that bill. In most cases the answer is yes and the exercise has cost five minutes. Occasionally the answer is that full take-up would sink the company, and in that situation what is being proposed is a bet on customers behaving in a particular way rather than a promotion in the ordinary sense. A bet can be a reasonable thing to place. The problem at Hoover was that nobody in the room had said out loud that a bet was what they were placing, so nobody asked whether they could afford to lose it.

There is a further lesson in the fact that the offer succeeded. It was designed to sell an enormous quantity of vacuum cleaners in the middle of a recession, and it did exactly that. The damage came from customers taking the offer at its word rather than from customers ignoring it. That is worth remembering whenever a promotion performs far beyond its forecast, because the moment an offer is going better than anyone planned is the moment the full take-up cost stops being a hypothetical and starts being the number the company will actually pay.

The case for offers that fail every rational test and win anyway is made by Rory Sutherland, and this entry is the example that shows where that argument stops. The habit of estimating from your own plan rather than from what happened to everyone who attempted something similar is the planning fallacy. And the one situation in which caution is arithmetic rather than fear, because a single loss can remove you from the game altogether, is described in loss aversion.

Thinking in Bets

Annie Duke, 2018

Duke's argument is that almost every decision is a bet, whether or not anyone in the room calls it one, and that the useful questions are how sure you are, what the possible outcomes look like, and what you can afford to lose. Hoover's promotion was a bet on two things about customer behaviour that nobody had tested, and the failure this entry describes is that it was approved as a marketing plan rather than named as the wager it was. Her book is the discipline for saying so out loud before the money goes in.
