The order is not binding for the COMPANY, before the Customer receives the confirmation of the acceptance of the order by the COMPANY, as described below. The order is considered received by COMPANY from the moment the Customer receives a relevant update of the order status with the indication “Confirmation of Order Entry“. Updates on the order status are displayed on the User’s screen and are sent by email to the contact email address registered by the User/Customer. The order status is continuously updated as well as when changes occur during the order management. The Customer must check the “Confirmation of Order Entry” and immediately inform the COMPANY (no later than within 2 hours from the time of receipt of the electronic notification marked “Order Entry”) in writing of any error, otherwise the data indicated in the “Confirmation of Order Entry” will be applied to the Sales Contract. During the processing of each registered order, the availability of stock of the products of the order is confirmed by the COMPANY. In case the availability or the delivery time differs from the one indicated on the product page, the Customer will receive a relevant notification. In particular, the COMPANY and if it determines the availability of the product and the lack of any errors in the online store regarding pricing or price of products, their characteristics, etc. by e-mail will confirm the acceptance of the order. The above e-mail will expressly confirm the content of the order, the total price, and the estimated time of delivery of the order, as it was already known to the Customer prior to the submission of the order. The order is considered binding and the sale is considered to have been concluded and creates claims of the contracting parties (Customer – COMPANY) only with the sending and receipt of the above-mentioned electronic message with the indication “Your order has been sent” or “Your order is ready for pickup“. The status of the order is constantly updated as well as when changes occur during the management of the Customer’s order. The Customer is obliged to check the status of the order and to immediately inform the COMPANY in writing of any error in the order, otherwise the data indicated in the Confirmation of receipt of the order will be applied to the sales contract.

In the event that in an order such an error in the price is found in only part of the ordered products, then the order is valid and executed normally for the remaining products and is considered not completed for the products in which the error was found, except in the case that the items in the order are related, are to be used as a single set and operate as a unit with each other and the Customer declares that the partial fulfillment of the order does not serve his needs or interests, in which case the COMPANY must cancel the entire order. In case of incorrect shipment of non-ordered products or services, their unconditional receipt or failure to inform the COMPANY and return the products cannot be considered as consent, acceptance or declaration of willingness to purchase them. In the event that a return is requested by COMPANY and the Customer delays returning such products for a period of more than seven (7) calendar days, then such refusal shall constitute a statement of intent to purchase the items and the order shall be deemed to have been confirmed and the Customer shall pay the value of the items.

The COMPANY reserves the availability of its products if they are not available at the time of the order. In this case, the COMPANY reserves the right not to accept the order in question and therefore not to conclude the sale. Any payments will be returned to the Client without undue delay, in the same way that the Client chose to pay for the order. Special cases of availability are the following:

  • Upon request: The product will be searched at a supplier of the COMPANY and the Customer will receive information about the availability of the product within 3-5 working days from the submission of the order.
  • With pre-order: The product is not in the supplier’s warehouse but can be ordered with an estimated delivery time. In this case, before the order is placed, the Customer is informed of the estimated time of arrival of the product. The confirmation of receipt by the COMPANY of the pre-order is only a confirmation that the order has been received with the content indicated and in no case constitutes acceptance of the order or agreement of terms (drawing up) of sale.
  • Temporarily Out of Stock: The product is out of stock or discontinued or not expected to be received immediately.
  • Offers & Coupons: The prices of these products are valid while stocks last. These products are subject to a strict order of priority in the execution of orders.

The COMPANY notifies each time to the Customer the estimated delivery time of the ordered product, depending on the circumstances. In any case, COMPANY undertakes to deliver the ordered product within thirty (30) days from the confirmation of receipt of the order. However, COMPANY reserves the right to inform the Customer in case of the existence of subsequent reasons that make the product unavailable or the possible (new) delivery time if there are reasons for delaying the delivery. In this case, if it is deemed that the delay makes the transaction unprofitable for the Customer, the Customer is entitled to unilaterally cancel the order by written declaration (by e-mail to If the order is cancelled and thus the sales contract is terminated, the COMPANY must refund, without undue delay, all the money paid by the Customer. Non-availability of part of the order: If the unavailability concerns only part of the ordered products of the order, the remainder of the order is normally executed, unless the products of the order are related, and are to be used as a whole, and the Customer declares that the partial execution of the order does not serve his needs or interests, in which case COMPANY must cancel the entire order.

To receive the order, the Customer must show the order confirmation (order code) and the notice of receipt, as well as an official identification document (such as an identity card or passport).

Given that after the receipt of the products, the risk passes to the Customer, the latter must check the products received upon receipt, since by signing the receipt, he confirms that he has correctly received the products of his order. Delivery at the place designated by the Customer: In case the product is shipped to the place chosen by the Customer, the product is delivered to an external partner – carrier and the Customer is informed electronically that the product is ready for shipment. Shipping costs are calculated based on the Customer’s order. Any incorrect entry by the Customer and therefore incorrect calculation of shipping costs is not borne by the COMPANY, but by the Customer.

For the receipt of the order, the Customer will show the external partner-carrier the order confirmation (order code) and the notification of shipment, as well as an official identification document (such as an identity card or passport). If the Customer wishes to authorize a third person to receive his order, then the third authorized person must show a special authorization to receive the specific order, legally certified by a KEP or a police or other authority, as well as an official document necessary for the verification of identity (identity card, passport, etc.). Since after the receipt of the products, the risk passes to the Customer, the latter must check the products received upon receipt, as with the order, the risk is transferred to the Customer. If the Customer does not receive the product after receiving the notice for shipment and despite the notice from the carrier, the COMPANY reserves the right to withdraw from the sale.

Force majeure: COMPANY is not responsible for delays in the execution of the order (including delivery) due to circumstances that cannot be attributed to the fault of COMPANY or due to force majeure and therefore COMPANY is entitled to an extension of time for execution. Indicative examples may include strikes, acts of terrorism, war, supplier/transportation/production problems, exchange rate fluctuations, governmental or legislative acts and natural disasters. If such events last for more than two (2) months, the sales contract may be terminated by either party without compensation.
