Price index

The same jar, a different price in every shop.

Dewbirdy re-reads every store it indexes each night and records what each one charges. That answers a question no single retailer can: how much does the same product vary between Australian shops?

Across 7,188 products carried by at least two Australian stores, in 39 stores and last checked 26 September 2026: a great deal.

The widest gap we can stand behind today is Omorovicza Blue Diamond Concentrate, from $598.00 to $771.00.

Products whose price range looks like a size or sample mismatch rather than a real difference are excluded — a $5 sachet grouped with a $200 device is arithmetic, not a saving. See methodology.

How to read this

A gap is not automatically a saving. Postage, pack size and how recently a store was checked all matter, which is why every product page carries its own crawl timestamp and links straight to the retailer so you can confirm before buying.

Figures are AUD, in stock, Australian stores only. An overseas price converted to AUD excludes international shipping and GST, so it is not comparable and is not counted here.

Using these numbers? Please link back to this page so readers can see the date they were measured on — they move every night.
