They all have .com.au websites now, all websites now look the same as each other, usually the same wordpress visual builders. They all offer AfterPay and claim to be based in Sydney or whatever. Google Products ranks them just the same as Harvey Norman and Amazon. But when you order from them you're order goes from some crazy network and then you're waiting over a month for it to process and ship from China. Or weeks later they might cancel your order.
And don't even get me started on how long regular Australia Post takes across state lines for real Australian sellers shipping straight from their stores. Australia Post sends it by Pony Express and an express package from China probably would have been faster anyway.
Which kind of leaves me only ordering from Amazon, unless I've had a previous good experience from another store, or they are obviously shipping from Australian warehouses.
