Terms of service
These Terms apply to your use of o3-performance.com and to purchases from O3 through our online store. Nothing in these Terms limits or excludes any right you have under mandatory consumer law.
1. Scope and order of precedence
1.1 These Terms apply together with our Shipping Policy, Return and Refund Policy and Privacy Policy, and with the information shown at checkout.
1.2 If these documents conflict, the information shown at checkout for your order prevails. Mandatory consumer law always prevails over all of them.
1.3 Our store is intended for consumers buying for personal use.
2. Products
2.1 We take care to describe and photograph our products accurately. Colours can look slightly different depending on your screen. Size guides are for guidance.
2.2 This does not affect your rights if a product does not match its description or is faulty.
3. Prices and currencies
3.1 Prices are shown in CHF, EUR, GBP or USD depending on your delivery country.
3.2 The total price, including delivery charges, is shown at checkout before you place your order.
3.3 Prices include any taxes that O3 collects for your delivery country, unless checkout states otherwise. Import duties, taxes and carrier fees that are not collected at checkout may be charged on delivery, as explained in our Shipping Policy.
3.4 Your bank or card provider may charge currency conversion fees. These are outside O3's control.
4. Pricing errors
4.1 If a product is listed at an obviously incorrect price, we will contact you before dispatch. You can then either confirm the order at the correct price or cancel it and receive a full refund.
4.2 If we cannot reach you, we will cancel the order and refund you in full.
5. How a contract is formed
5.1 During checkout you can review your order and correct input errors before you click the button to place your order and pay. Clicking that button is an offer to buy the selected products and creates an obligation to pay.
5.2 The email we send after you place your order confirms that we have received it. The contract is formed when we send you the email confirming that your order has been dispatched.
5.3 Payment is taken when you place your order. If we do not accept your order, we will refund you in full without undue delay.
5.4 The contract language is English. Your order details are available in your order emails and, if you have one, in your customer account.
6. When we may decline an order
6.1 Before dispatch, we may decline an order only for a genuine reason, namely:
- the product is unavailable
- payment is not authorised
- the order information is materially incomplete or incorrect
- a pricing error under section 4
- a reasonable suspicion of fraud
- delivery to the destination would be unlawful
6.2 In each case we will tell you and refund any amount paid in full.
7. Payment
7.1 You can pay with the methods shown at checkout. By paying, you confirm that you are authorised to use the payment method.
7.2 Security checks may delay dispatch. If a check delays your order beyond the processing time in our Shipping Policy, we will tell you.
8. Delivery
8.1 We ship to the destinations listed in our Shipping Policy. Orders are processed within up to 5 business days before dispatch, followed by the carrier's delivery time.
8.2 Where no delivery date has been agreed, we will deliver without undue delay and no later than 30 days after the contract is formed.
8.3 If we do not deliver on time, you have the rights provided by applicable law. These include setting an additional period for delivery and, if we do not deliver within it, ending the contract and receiving a full refund.
8.4 O3 bears the risk of loss or damage until the goods are delivered to you or to a person or place you have nominated. Ownership passes to you on delivery.
