False advertising

I saw an item on edgars website, Jxchange navy men's chino prices from R149.95. I wanted the item asap so I went into store and the exact same item was R300. I was simply advised that all the online prices differ from store prices. This is ridiculous! All other retailers, if their online price differ from the store state that its an online exclusive or available online only. I queried this instore -canal walk cape town- and am advised I will be contacted today still no callback. This is unacceptable and in contravention of Section 30 of the CPA.
