They don't compare eggs with eggs either. They compare items in the same category that may be vastly different in quality, or be completely different items despite being in the same category. Two items may be identical in almost all respects but one may have a more popular picture on it so the price will stay up. They also don't take into account that a Chinese seller may have the same product at a fraction of the Australian price. They also don't take into account the fact that the cheaper sellers may have very dodgy feedback, which isn't a fair assessment of an item's normal selling price.
