I ordered a MacBook Pro (though Pink/Rose Gold) for 29999.99 RSD (255.46 €, 279.63 $). It was supposed to cost 299999.99 -- 2,796.29 $ or 2,554.55 € (extra 9). The order was cancelled with no explanation, obviously. Laws in Serbia do allow for a sale to be cancelled before delivery if the merchant entered the wrong price, or the device is not available in the warehouse, etc. It was funny :)
That kind of thing happens in Australia and the sale must go ahead by law. The advertised price is the price, end of story.
I think I've read about people in USA suing companies for refusing to sell, or requesting return, of products that were advertised with "incorrect" prices and ordered/purchased by the customer.
