These eBay 20% discounts from certain retailers are nothing but misleading and deceptive and should be investigated by the ACCC.

For example the 20% discount on the Dick Smith Store that ran from Sunday to Thursday. They edited many items Friday afternoon prior to the sale starting to add on ~20% and removed the ~20% the day after this sale ended (Friday).

For example look at the changes to this listing, I suspect they have something that updates postage information on a regular basis to attemp to concel the changes to price.

Revision history

http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItemRevisionDetails&item=251596756663&rt=nc&_trksid=p204...

Changed to $428 from $363.

(Price increased by around 20% - over their previous price and their website price).

and the next day after the sale ended dropped to $363.

(Price decreased by around 20% - matching their website)

If eBay are going to allow these retailers to pull these scams the ACCC should be looking at them as well, eBay is running the 20% discount and should be policing the retailers but I suspect that eBay are well aware that these retailers jack the price up.

Was $866, price increased to $896 whilst the same product on their website was $796.

and the change back just after midnight to $796 which is the same price it's been at for at least a week on their website.
