Ordering, Conclusion of Contract

An order constitutes an offer to WormUp to conclude a contract. Upon submission of the order, the customer automatically receives an acknowledgment of receipt (or order confirmation) confirming that the order has been received by WormUp.

WormUp reserves the right to reject orders in whole or in part without stating reasons. In this case, the customer will be informed, and any payments already made will be refunded. Further claims are excluded, in particular, there is no subsequent delivery of unavailable products.

Delivery Conditions, Delivery Times, Delivery Costs

General Delivery Conditions

After payment is received, the ordered goods will be dispatched according to the delivery times listed on the online shop. We only deliver by shipping; self-collection of goods is not possible. We do not deliver compost worms to packing stations.

Temporal deviations are possible, especially on peak days with exceptionally high delivery volumes, with any claims for damages and other claims by the customer being excluded. If not all items are immediately available, it is at WormUp's discretion to make partial deliveries.

The delivery of goods is made by shipping to the delivery address provided by you, unless otherwise agreed. The delivery address specified in our order processing is decisive for the transaction.

At the time of delivery, the customer assumes responsibility for the delivered goods, even if they were not directly received by them.

If the transport company returns the shipped goods to WormUp because delivery to you was not possible, you bear the costs for the unsuccessful shipping. This does not apply if you validly exercise your right of withdrawal, if you are not responsible for the circumstance that led to the impossibility of delivery, or if you were temporarily prevented from accepting the offered service, unless WormUp had announced the service to you a reasonable time in advance.

Any delay in delivery does not entitle the buyer to withdraw from the purchase contract or to claim damages against WormUp.

Delivery Conditions for Living Products

Worms are living products. Worms tolerate temperatures above 25°C (e.g., in the mailbox) or temperatures below 5°C poorly. To ensure that the worms arrive healthy and optimal, we only ship at temperatures between 5° - 25° Celsius. The compost worms are shipped at the ideal shipping time without specifying a desired delivery date.

Please ensure that you are present on the day of delivery in the height of summer and winter or that someone takes delivery from the mailbox for you. Ensure that the worms are spread on the day of arrival or, at most, stored cool for a short time.

Delivery Costs

The delivery costs depend on the value of the ordered goods and the destination country. The delivery costs communicated in the online shop apply. The delivery costs are listed as an additional item in the shopping cart and on the invoice.


WormUp determines which payment method is offered for each order, and this is visible during the payment process. In principle, payment can be made using one of the following payment methods: credit card (Master/Visa), TWINT, PostFinance Card/e-Finance, or by invoice.

If open claims arise due to refunds during payment, the repayment will be made within 30 days to the account used for the purchase. The period begins upon receipt of the goods by WormUp.

Retention of Title

The goods remain our property until full payment has been received.

Right of Return

For returns, only the purchase price without the originally incurred shipping costs will be refunded. The refund of the purchase price will be made through the same payment method as the original payment was received.



General Provisions

WormUp is committed to diligence and generally delivers goods of good quality.

In the event of defects in the delivered goods, WormUp is entitled to rectify them or deliver new ones. If rectification or replacement is not possible, the customer may demand rescission or reduction in accordance with the provisions of Swiss law. Any refund will always be made through the same payment method as the payment was received.

Excluded from warranty are defects that WormUp is not responsible for, such as natural wear and tear, force majeure, improper handling, interventions by the customer or third parties, excessive use or extreme environmental influences, as well as comparable other causes.

Since we cannot monitor the proper application of our products in practice, we only assume liability for the consistent quality of our products at the time of delivery. The customer is responsible for checking the usability of the products on their own.

Obvious defects must be reported immediately, but no later than within 7 days.

Changes to the patina of the clay worm composter are part of the natural process and do not constitute a defect.

Special Provisions: Compost Worms as Living Animals

Our worms are checked for activity before shipping. If you receive lower quality for any reason, please call us immediately. We reject any claims for replacement if reported late.

Ensure that the worms are spread on the day of arrival.


Unless otherwise stated below, further claims of the purchaser - regardless of the legal basis - are excluded. We are not liable for damages that did not arise from the delivery item itself; in particular, not for lost profit or other financial losses of the purchaser. To the extent that liability is excluded, this also applies to the personal liability of employees, representatives, and vicarious agents. The aforementioned limitation of liability does not apply if the cause of the damage is based on intent or gross negligence or if there is personal injury or the Product Liability Act applies.

In the case of other breaches of duty, we are only liable for intent and gross negligence. This limitation also applies to the legal representatives, employees, staff, employees, and vicarious agents of ours.
