RRP is $50 I believe. A staple ring at Pandora that is on sale for some reason, might be getting discontinued soon maybe? Good for stacking with some other rings. Pandora has very few sales and they're usually on seasonal stock only so this is quite a steal!
There's quite a few items in their sale below the RRP: https://estore-au.pandora.net/sale/?icid=e:homepage:homepage…
Also note that the AU store is generally cheaper than the US, EU or Asian stores, except maybe deals on La la rue.
