- If the Competitor has that item in stock and displays it on their website
- If you have a written quote from the Competitor indicating the price and availability if that information is not readily available on their website.
WE CANNOT PRICE MATCH:
- Items that are not in stock at the Competitor or the price and availability is not clearly indicated
- Special bulk or discount bundles, clearance products, second-hand, refurbished or display stock or exclusive member deals offered by the Competitor

- International dealers or unauthorised distributors that are selling international goods direct to Australian consumers
