In Australia, there are many retailers who will be competing to bring the best deals and discounts on Black Friday. As for which retailer will have the best Black Friday deals, that will really depend on which category you plan to buy in. For instance, Amazon, The Good Guys, JB Hi-Fi and Harvey Norman usually offer the biggest savings on 4K TVs, smartphones and appliances. That said, those after a new PC or laptop should consider buying direct from brands such as Dell and HP. Additionally, it's worth keeping an eye on eBay Australia, which will offer discounts on practically everything, with even bigger savings for eBay Plus members.
