Online pricing error not honoured

Incredible Connection online store had a western digital 2TB portable hard drive on offer for R169, I assumed it was a clearance offer and since the offer was from 11 to 14 June, I thought I could go online and purchase on the morning of the 12th. when I went online the price was changed to R1499 and there was no message to state that the price was originally incorrect and now corrected, I contacted the customer query dept. via email and got 2 email responses with a disclaimer stating that the price was incorrect. the attitude from their staff Jody and Joshua was extremely poor and they just had a sorry for you attitude stating their company policy was that prices can be updated at any time. My problem is firstly since there was no disclaimer about the error when I went online the second time, then the price I saw on the first occasion should be honoured. the final answer I got from Jody was that if I processed the order when the incorrect price was up I would have received the item at R169, but what If I had a print add and went into store and there was no disclaimer, you would have no option but to give it to me at the lower price, why does an online purchase differ, Bad Service
