Coronavirus pandemic and people's panic is a good way to make money on them for stores. It has become known recently that some stores in Sydney speculate with the most needed goods. One customer shared a photo of a bottle with antiseptic which cost 25 dollars, usually it costs less than 10 dollars. Moreover, there was no legal sticker on that. That means that the store bought it and now resells, but much more expensive. The same situation is with medical masks, which cost in some stores 10 dollars now, with normal price of 20 cents.
But that is not the worst example. In another Sydney shop you can find the same bottle of antiseptic (450 ml) which costs 50 dollars.
Some stores do such "frauds" with toilet paper. One roll costs3 dollars, as usual. But two rolls will cost already 99 dollars. The owners say it is done to avoid deficit and people's greed.
