This issue of displaying fake "was" prices is often mentioned in deals but never actually enforced. Seems Chemist Warehouse was selling items on their website claiming savings from their RRP, a price that they had never sold the item for.
The ACCC considered that by displaying on its website statements next to images of certain Healthy Care products including:
‘Don’t Pay RRP $39.99’ ; and
‘Save $18.00’,
Epharmacy represented to consumers that by purchasing these products from the My Chemist, Epharmacy, or Chemist Warehouse websites they would save the specified amount off the RRP. In fact, the products had never been offered for sale at the RRP by those or any other retailers.
Wow, that's dirty!
