§ 3 Conclusion of the contract

(1) The subject of the contract is the sale of goods .

(2) By listing the respective product on our website, we make you a binding offer to conclude a contract via the online shopping cart system under the conditions specified in the product description. 

(3) The contract is concluded via the online shopping cart system as follows:
The goods intended for purchase  are placed in the "shopping cart." You can access the "shopping cart" at any time via the corresponding button in the navigation bar and make changes there.
After clicking the "Checkout" or "Proceed to Order" button  (or similar designation) and after entering personal data as well as payment and shipping conditions, the order data will finally be displayed to you as an order overview.

If you use an instant payment system (e.g., PayPal (Express/Plus/Checkout), Amazon Pay, Sofort) as your payment method, you will either be directed to the order overview page in our online shop or redirected to the website of the instant payment system provider.
If you are redirected to the respective instant payment system, you make the corresponding selection or enter your data there. Finally, the order data will be displayed as an order overview on the website of the instant payment system provider or after you are redirected back to our online shop.

Before submitting the order, you have the option to review, change (also using the "back" function of your internet browser), or cancel the order in the order overview.

(4) Your inquiries for creating an offer are non-binding for you. We will submit a binding offer to you in text form (e.g., by email), which you can accept within 5 days (unless a different deadline is specified in the respective offer).

(5) The processing of the order and transmission of all information required in connection with the conclusion of the contract is carried out partly automatically by email. Therefore, you must ensure that the email address you have provided to us is correct, that the receipt of emails is technically ensured, and in particular, that it is not blocked by spam filters.

§ 4 Custom Designed Goods

(1) You will provide us with the suitable information, texts, or files required for the individual design of the goods via the online ordering system or by email no later than immediately after the conclusion of the contract. Any specifications regarding file formats must be observed.
 
(2) You agree not to transmit any data whose content infringes on the rights of third parties (especially copyrights, name rights, trademark rights) or violates existing laws. You expressly indemnify us from all claims made by third parties in this context. This also includes the costs of any necessary legal representation in this context.
 
(3) We do not verify the transmitted data for accuracy and therefore assume no liability for errors.

§ 6 Provision of services for vouchers (voucher conditions)

(1) Unless otherwise stated in the offer or on the voucher, we are the issuer of the voucher. Our name and address can be found in our contact details in the imprint.

(2) Purchased vouchers entitle you to services from us within the validity period (validity duration). Vouchers can only be redeemed in our online shop at celumiu.com or, if specified, in our local store on site. The service description and the redemption conditions described there at the time of voucher purchase apply.

(3) The validity period of the voucher is 3 years from the date of purchase until the end of the calendar year, unless a different validity period is specified in the respective offer.

(4) The prerequisite for redeeming a voucher is full payment of the purchase price for the voucher. The voucher must be redeemed during the electronic ordering process on our website by entering the voucher code in the designated input field. Subsequent crediting is excluded. Any remaining balance remains on the voucher and can be used for further orders.

(5) Only one voucher can be redeemed per order.

(6) After the withdrawal period has expired or the right of withdrawal for consumers has lapsed, no refund or exchange will be made. Payment or partial payment of voucher amounts is not possible. The voucher balance does not accrue interest. If the statutory right of withdrawal is exercised for goods or services paid for with the voucher, the voucher amount included in the purchase price will be credited exclusively as a voucher. Unless otherwise stated, the validity period of the credited voucher corresponds to the validity period of the voucher used for the order.

(7) Transfer or assignment of the voucher is permitted.

§ 7 Right of Retention, Retention of Title

(1) You may only exercise a right of retention insofar as it concerns claims from the same contractual relationship.

(2) The goods remain our property until full payment of the purchase price.

(3) If you are an entrepreneur, the following applies additionally:

a) We retain ownership of the goods until all claims arising from the ongoing business relationship have been fully settled. Prior to the transfer of ownership of the reserved goods, pledging or security transfer is not permitted.

b) You may resell the goods in the ordinary course of business. In this case, you hereby assign to us all claims arising from the resale in the amount of the invoice value, and we accept the assignment. You are still authorized to collect the claim. However, if you do not properly fulfill your payment obligations, we reserve the right to collect the claim ourselves.

c) In the event of connection and mixing of the reserved goods, we acquire co-ownership of the new item in proportion to the invoice value of the reserved goods relative to the other processed items at the time of processing.

d) We undertake to release the securities due to us at your request to the extent that the realizable value of our securities exceeds the secured claim by more than 10%. The selection of the securities to be released is at our discretion.

§ 8 Warranty

(1) Statutory defect liability rights apply.

(2) As a consumer, you are requested to immediately check the goods upon delivery for completeness, obvious defects, and transport damage and to notify us and the carrier of any complaints as soon as possible. Failure to do so does not affect your statutory warranty rights.

(3) If a characteristic of the goods deviates from the objective requirements, the deviation is only considered agreed if you were informed of it by us before submitting the contract declaration and the deviation was expressly and separately agreed between the contracting parties.

(4) If you are an entrepreneur, the following warranty provisions apply instead of the above:

a)  Only our own specifications and the manufacturer's product description are considered agreed as the condition of the goods; other advertising, public promotions, and statements by the manufacturer are not.

b)  In case of defects, we provide warranty at our discretion through repair or replacement. If the defect remedy fails, you may demand a reduction or withdraw from the contract at your choice. The defect remedy is considered failed after an unsuccessful second attempt, unless otherwise indicated by the nature of the goods, the defect, or other circumstances. In the case of repair, we are not obliged to bear the increased costs caused by transporting the goods to a location other than the place of performance, provided the transport does not correspond to the intended use of the goods.

c)  The warranty period is one year from the delivery of the goods. The shortening of the period does not apply:

- für uns zurechenbare schuldhaft verursachte Schäden aus der Verletzung des Lebens, des Körpers oder der Gesundheit und bei vorsätzlich oder grob fahrlässig verursachten sonstigen Schäden;
- soweit wir den Mangel arglistig verschwiegen oder eine Garantie für die Beschaffenheit der Sache übernommen haben;
- bei Sachen, die entsprechend ihrer üblichen Verwendungsweise für ein Bauwerk verwendet worden sind und dessen Mangelhaftigkeit verursacht haben;
- bei gesetzlichen Rückgriffsansprüchen, die Sie im Zusammenhang mit Mängelrechten gegen uns haben.

§ 9 Rechtswahl, Erfüllungsort, Gerichtsstand

(1) Es gilt deutsches Recht. Bei Verbrauchern gilt diese Rechtswahl nur, soweit hierdurch der durch zwingende Bestimmungen des Rechts des Staates des gewöhnlichen Aufenthaltes des Verbrauchers gewährte Schutz nicht entzogen wird (Günstigkeitsprinzip).

(2) Erfüllungsort für alle Leistungen aus den mit uns bestehenden Geschäftsbeziehungen sowie Gerichtsstand ist unser Sitz, soweit Sie nicht Verbraucher, sondern Kaufmann, juristische Person des öffentlichen Rechts oder öffentlich-rechtliches Sondervermögen sind. Dasselbe gilt, wenn Sie keinen allgemeinen Gerichtsstand in Deutschland oder der EU haben oder der Wohnsitz oder gewöhnliche Aufenthalt im Zeitpunkt der Klageerhebung nicht bekannt ist. Die Befugnis, auch das Gericht an einem anderen gesetzlichen Gerichtsstand anzurufen, bleibt hiervon unberührt.

(3) Die Bestimmungen des UN-Kaufrechts finden ausdrücklich keine Anwendung.
