If a product doesn't work for you, we'll make it right. No complicated processes, no unreasonable conditions. Here's exactly how it works.
If you don't see the results you expected from any supplement, contact us within 90 days of purchase and we'll issue a full refund — no questions about why, no restocking fee.
Three steps, handled via email. We aim to make this as friction-free as possible.
Send a message to info@optimoz.com.au with your order number and a brief description of the issue. You'll hear back within one business day.
For approved returns within Australia, we'll email you a prepaid return label. There's no cost to you for return shipping on eligible items.
Once we receive and inspect the item, we'll process your refund to the original payment method. You'll receive a confirmation email when it's done.
Different situations are handled differently — here's what to expect in each case.
Contact us within 90 days of purchase. Return any remaining unopened product and we'll refund in full. This applies to all supplements in our range.
Send us a photo and we'll despatch a replacement or process a full refund immediately — no need to return the item.
We'll accept a return within 90 days if the item is unopened and in original packaging. Return shipping is at your cost for change-of-mind returns.
If the item was shipped directly to you as a gift recipient, we'll issue store credit to you. If it was shipped to the gift giver first, any refund will go back to them.
We're Sydney-based, so processing times may vary by state. Here's a typical breakdown.
If your refund hasn't appeared after 5 business days of receiving your confirmation email, first check with your bank or PayPal directly — processing delays are common. If you've done that and still can't see it, contact us at info@optimoz.com.au.
A small number of items and situations fall outside our standard policy.
Devices and tech products have their own warranty terms.
HeartMath offers a two-year international warranty from date of purchase. If you're experiencing technical difficulties, contact HeartMath support directly at support@heartmath.com in the first instance — they will diagnose the issue and authorise a warranty replacement if necessary. Please choose your device version carefully before purchase, as refunds and exchanges on HeartMath products are assessed case by case.
If you'd like to exchange a product for a different size, format, or item of the same value, email us and we'll do our best to accommodate. Exchanges are subject to stock availability and must be initiated within 90 days of purchase. The product being exchanged must be unopened and in its original condition.
Australian Consumer Law: Our 90-day satisfaction guarantee is offered in addition to, and does not limit, your rights under the Australian Consumer Law. If a product is faulty, unsafe, or not as described, you may be entitled to a remedy under ACL regardless of the timeframe above.
Our team responds to emails within one business day. WhatsApp is also available for quick questions.
