Apple Inc. mispriced a computer model on its Taiwan online store Friday, listing its Mac Mini at NT$19,900 (US$620), close to 40 percent of its regular price of NT$47,710. The pricing error of was discovered on the Education Apple Store Taiwan's website around Friday noon. The company has not commented on the issue. The price listed for the 8GB version of the computer model -- the Mac Mini Snow3 Leopard Server -- was even lower than the 4 GB version, which is priced at NT$34,900. The error was corrected around 7 p.m. Friday but by then the site had received orders for up to 200,000 units at the incorrect price, according to local media reports. Lee Mai, deputy director of the Commerce Department under the Ministry of Economic Affairs, said although the regulations on Internet transactions will not take effect until 2011, Apple could face lawsuits over the incident if it is not willing to deliver the mispriced computers. The Cabinet-level Consumer Protection Commission said online orders are considered as effective contracts, therefore sellers must deliver their orders, even if they have been mispriced. Lee said that according to the proposed regulations on website transactions, sellers -- with legitimate reasons -- can reject orders within two days. However, if the buyers have already paid for their purchases, the orders must be delivered, Lee added. A year ago, Dell Computer experienced a similar mispricing problem, on June 25 and July 5, involving nearly 200,000 online orders. On July 1, the economic ministry's Petitions and Appeals Committee rejected an appeal by Dell and ruled that the computer giant should pay a fine of NT$1 million for the two online pricing errors.
