Ever since e-commerce began there have been stories of mispriced items -- and following that, stories of the mad rush to buy the mispriced product (especially when it involves misplaced decimals, shrinking the price by orders of magnitude). In the US, at least, it's quite clear that such a mispricing need not be honored by the retailer, though public pressure often leads the retailer to offer something
to those who tried to buy, just for the sake of PR. Given that, it's quite surprising to see Taiwan regulators tell Dell that it needs to honor the 140,000 monitors that were sold for about $15 each
when they really were supposed to be $150. It's difficult to see how it makes sense to enforce the lower price. It was a clear mistake, and most of the orders were clearly only made due to the mistake.
