If the Seller again exceeds this period, the Customer has the right to cancel the order.

11.2 Where any liability exists, the Seller is only liable for direct damage. Any liability of the Seller towards the Customer for direct damage due to intent or gross negligence is limited, per event (a related series of events being regarded as a single event), to replacing the defective Products or refunding their price, at the Seller’s discretion. No other damages may be claimed. Liability for indirect damage, including loss of profit, consequential damage, losses incurred, missed savings and damage due to business interruption, is expressly excluded.

12. Right of withdrawal

12.1 The Customer has a statutory right to withdraw from the Contract during the period specified in Article 12.2. The Customer must inform the Seller of their decision to withdraw from the Contract in order to receive a refund. The Customer is not required to give a reason for the withdrawal.

12.2 The Customer has fourteen (14) days to withdraw from the Contract. The starting point of this period may vary. The following rules apply:

  • If the delivery concerns a single Product, the period begins the day after the Customer receives the Product.
  • If the delivery concerns multiple Products delivered on separate days, the period begins the day after the Customer receives the last Product ordered.
  • If the delivery concerns a Product supplied over a certain period, the period begins the day after the Customer receives the first delivery of the Products.
  • If the delivery concerns a service contract, the period begins on the day the Contract was concluded.

12.3 In accordance with Article VI.53 of the Belgian Code of Economic Law, the Customer may not exercise the right of withdrawal referred to in Article 12.1 in the cases exhaustively listed therein. This applies, among other things, to the delivery of goods that are liable to deteriorate or expire rapidly. As the products offered by the Seller (such as, among others, living organisms, nematodes and predatory mites) are of a nature that deteriorates rapidly and/or has a limited shelf life, the right of withdrawal is excluded for these products.

12.4 If the Customer decides to withdraw from the Contract, they must inform the Seller by an unambiguous statement, by registered post or by e-mail to the address stated in Article 1.1 of these Terms and Conditions, or by completing the model form included as an annex to these Terms and Conditions. The Customer must return the Products to the Seller without undue delay and, in any event, no later than fourteen (14) calendar days after sending the notice of withdrawal to the Seller. The Products must be returned to the Seller in the same manner in which the Customer received them. The costs of doing so are borne entirely by the Customer.

12.5 During the first 14 days after receipt, we ask you to handle the Products with care, as well as the packaging. Products should only be unpacked or used to the extent necessary to assess whether they meet your needs. Any returned Product must be returned complete, including all individual parts or accompanying accessories, and in its original condition. Where possible, returns should be made in the original packaging, in accordance with our instructions.

12.6 In the event of withdrawal:

  • The Seller will refund the amounts already paid by the Customer for the Products upon receipt of the Products. The Seller may, however, reduce the refund to account for any reduction in the value of the Products, if this results from the Customer having handled them in a way that would not be permitted in a shop.
  • The Seller will process all refunds within fourteen (14) days of receiving the Products.
  • The Seller will refund the Customer using the same means of payment as the Customer used to place the order.
  • Where the Products have been used in a way that goes beyond simply assessing them, a reduction in value may be established. In such cases, the Seller has the right to deduct this reduction in value from the refund.

13. Warranty

13.1 The Customer is entitled to a statutory warranty of two (2) years. For second-hand goods, the Customer is entitled to a statutory warranty of one (1) year. The statutory warranty covers any defect or lack of conformity of the Products that becomes apparent within two years of the delivery date. If a defect becomes apparent within this warranty period, it is presumed to have existed prior to delivery. This presumption may be rebutted if the Seller proves otherwise.

13.2 The Customer must inform the Seller, by registered post or by e-mail to the address stated in Article 1.1, of defective Products within a reasonable time and no later than two (2) months after the defect was discovered or could reasonably have been discovered by the Customer.

13.3 The Customer must return the Products to the Seller without undue delay and, in any event, no later than fourteen (14) days after sending notice of the defect to the Seller. The Products must be sent to the Seller in the same manner in which the Customer received them. Once the defective Product has been returned, the Seller will, at the Customer’s choice, send a new Product or repair the Product, and the Seller will bear all costs associated with the exchange or repair. A Product can only be replaced to the extent that it is still available from the Seller’s suppliers. If repair or replacement is not possible, or cannot be carried out within a reasonable period, the Customer has the right to terminate the Contract. In that case:

  • The Seller will refund the amounts already paid by the Customer for the Products upon receipt of the Products.
  • The Seller will process all refunds within fourteen (14) days of receiving the Products.
  • The Seller will refund the Customer using the same means of payment as used to place the order, unless the Customer has expressly agreed to a different means of payment which does not entail any additional cost to the Customer.

14. Complaints procedure

14.1 If the Customer has a complaint, they may contact the Seller using the contact details stated in Article 1.1 of these Terms and Conditions.

14.2 If the dispute cannot be settled amicably, the Customer may file a complaint with the Consumer Mediation Service, address: Boulevard du Roi Albert II 8 Bte 1, 1000 Brussels, Belgium (North Gate II).

14.3 If the Seller and the Customer are unable to reach an agreement, the consumer may also always turn to Becom. Becom will mediate between the consumer and the Seller if the complaint appears well-founded at first sight. You can reach them via the online complaints form at https://becom.digital/nl/consumers-complaints/, or in writing at: Rue du Marquis 1, 1000 Brussels, Belgium, [email protected].

15. Transfer and subcontracting

15.1 The Seller is entitled to transfer its rights and obligations under the Contract to a supplier (for example, for the delivery of the Product), without this affecting the rights and obligations under these Terms and Conditions.

15.2 If the Customer has purchased a Product as a gift, they may transfer the warranty referred to in Article 13 to the recipient of the gift without needing the Seller’s consent.

16. Force majeure

16.1 The Seller is not liable or responsible for any failure to perform, or delay in performing, its obligations under the Contract where this is due to force majeure.

16.2 In the event of force majeure, the Seller will notify the Customer, and the Seller’s obligations under the Contract will be suspended, with the period for performance extended for the duration of the force majeure event. Where this affects delivery of the Products, the Seller will agree a new delivery date with the Customer once the force majeure event has ended.

17. Applicable law

17.1 These Terms and Conditions are governed by Belgian law. This means that Contracts for the purchase of Products via the Website, and any disputes or claims arising from or related to them, are governed by Belgian law.

18. Final provisions

18.1 The Seller may amend these Terms and Conditions at any time. The Terms and Conditions in force at the time the Products are ordered will apply to the Contract between the Customer and the Seller. The invalidity of any provision, or part of a provision, will not affect the validity of the remainder of that provision or of the other clauses.
