This exact scenario happened recently at a major European electronics chain. Loyalty cardholders discovered tablet computers listed at ninety-eight percent off the regular price. The deal appeared legitimate because it was near Black Friday, when extreme discounts are common. Customers ordered online and chose in-store pickup. Within an hour, they received confirmation emails. When they arrived at stores, their payments processed smoothly and the tablets were handed over without any questions.

However, eleven days later, those same customers received a surprising email. The retailer claimed the price was clearly an error—a technical glitch on their platform. They offered two options: pay most of the original price to keep the tablet (although with a modest discount), or return it for a refund plus a small voucher.

This situation raises a fascinating legal question: when is a price mistake actually binding? The answer depends largely on something called recognizability. Many legal systems allow contracts to be voided if an error is both fundamental and recognizable to the other party. But what makes an error recognizable?

Consumer law experts point out that modern retail has made this question much harder to answer. Twenty years ago, a ninety-eight percent discount would have been obviously wrong. Today, however, flash sales, app-only deals, and viral marketing stunts have made extreme discounts part of the landscape. Therefore, a customer might reasonably think a massive discount is a loss-leader promotion or a social media marketing campaign.

The legal analysis often turns on the buyer’s sophistication. Consider two scenarios. In the first, a casual shopper spots the deal, thinks they’ve gotten lucky, and buys one tablet for personal use. In the second, someone purchases five tablets and immediately lists them for resale. The second buyer’s awareness of the error seems more obvious.

Similar cases have played out elsewhere. Airlines have accidentally listed business class tickets at economy prices. Hotels have offered luxury suites for the cost of standard rooms. In some jurisdictions, courts have sided with consumers, ruling that a published price is an offer that, once accepted, creates a binding contract. In others, judges have allowed sellers to void transactions when errors are sufficiently extreme.

The timing matters too. In this case, the retailer completed the transactions, accepted payment, and handed over products before raising any objection. That’s different from catching an error before fulfillment and canceling orders.

What makes this case particularly interesting for students of contract law is the gray area it occupies. It’s not clearly fraud by the buyer—most purchased just one item for personal use. It’s not clearly binding either, given the magnitude of the pricing error. It sits in that uncomfortable middle ground where reasonable people disagree about what’s fair and what’s legal.
