Common questions
How curation, returns and credit work across the shop.
How do we curate our products?
Every product on ORUS goes through a three-step process. We research the category, test the product ourselves, and verify the claims against published evidence. If it does not do what it says, it does not make the shop.
Can I return a product if it does not work for me?
Yes. 14-day returns on unused, unopened items, counted from delivery. If it does not suit you, send it back; a change of mind is posted at your cost.
How does the advisor work?
The ORUS advisor is an AI that learns your sleep patterns, sensitivities, and routine. It recommends products based on what you actually need, not what is trending. Every conversation picks up where you left off.
Do you ship internationally?
We deliver within the UK and within Malaysia. UK delivery is £3.95, free over £50; Malaysia is RM10, free over RM150. Singapore and Australia are priced at checkout, and checkout shows the delivery for the address you give.
How do ORUS credits work?
An order placed with a discount code earns 2% back in ORUS credit, and ORUS+ members will earn 5% on every order once ORUS+ launches. Gold (£250 spent in a year) earns 3.5% and Platinum (£750) earns 5% on those orders. Your credit comes off at checkout on orders paid in pounds.
