TANDEM reserves the right to adapt or change these general terms and conditions at any time, with the version thereof applicable to any transaction being that which appears on line on the site at the time of the order.

Article 1 – The Customer

The Customer declares that he is a natural person at least 18 years of age and that he has the legal status or is the holder of a parental authority that authorizes him to place an order on the site. Upon the recording of his personal data in the « my account » rubric, the Customer must verify the accuracy and comprehensiveness of the data he provided for the carrying out of the service involved. In the event of an error in the recipient's identification data, TANDEM shall not be accountable for non-delivery of the product involved. TANDEM reserves the right to cancel any order when the Customer's IP address is domiciled in a country different from the billing and/or delivery address.

Article 2 – The Products

The products offered for sale are those described on the site. The products offered by TANDEM comply with the standards applicable in France.
TANDEM is particularly attentive to the display and description of its products in order to inform the Customer in the best possible way. However, insignificant errors may appear on the site, which the Customer acknowledges and accepts. In any event, if a product delivered to the Customer does not correspond to its description on the site, the Customer may either exercise his right of retraction or put TANDEM's conformity guarantee into play, with TANDEM then exchanging the product or refunding all or any part of the price thereof that might have been billed.

Article 3 – The Order

The placement of an order on the site is subject to compliance with the procedure implemented by TANDEM, which consists of a succession of various steps that the Customer must take in order to validate his order. The Customer may verify the detail and total price of his order, and correct any possible errors, before confirming and accepting his order. An order confirmed by the Customer is deemed to be a contract of sale and acceptance of all of the general terms and conditions of sale.

If, despite TANDEM's vigilance, products are unavailable, it will promptly inform the Customer thereof by email. The Customer may then cancel his order and be refunded the amounts he has already paid.
Under no circumstance shall TANDEM incur any liability for the definitive or temporary unavailability of products. Neither shall any such unavailability give the Customer the right to claim any indemnification or damages.

TANDEM reserves the right to refuse any order of a Customer with which there is a dispute or an incident related to the payment of a prior order, or which contravenes the provisions of these general terms and conditions of sale.

If that event, TANDEM will inform the Customer by email. If the Customer fails to correct the elements that are erroneous or contrary to these general terms and conditions of sale, TANDEM reserves the right to refuse to process the order.

TANDEM will send the Customer a confirmation email summarizing the order (products, price, availability, quantity, etc.). To that end, the Customer expressly agrees to the use of his email address for confirmation of the content of his order by TANDEM. In any event, the invoices are issued upon delivery.
