You're right, my bad. To clarify, I chose dishwasher tablets as a common product among many I've noticed sharply increase in price here in Australia.
AUD $48 for a pack of 32 tablets is about USD $32. When I look on Walmart US site, they are selling the same brand and similar product (Finish Powerball Quantum) in a 50 pack for USD $15 which is about AUD $22. I don't expect Australia to be the same equivalent price, but the price difference here is crazy.
I have no idea how much dishwasher tablets ought to cost, but you've applied the exchange rate in reverse. $1.50 AUD is currently about $1 USD.
