PriceHound automatically scans major Australian retailers multiple times daily, comparing prices in real-time. We track price history so you can see if a deal is genuinely good or just looks like one.

We update prices multiple times per day. However, retailer prices can change at any time. Always confirm the final price on the retailer's website before completing your purchase. The 'Last checked' timestamp on each listing shows how recently we verified the price.

No — PriceHound is a price comparison service. When you click 'Go to Store', you're taken directly to the retailer's website to complete the purchase. We don't handle payments or orders.

Click the 'Price Alert' button on any product page and enter your target price. We'll email you as soon as the price drops below your threshold. You can manage your alerts from your account dashboard.

Yes, PriceHound is completely free for consumers. We earn a small commission from some retailers when you click through and make a purchase, which is how we keep the lights on. This never affects the prices you see.
