zooplus offers you the best price!

Text: zooplus is the market leader for pet supplies online. That's how we can afford to offer you prices at the level of the best pet shops around - often, zooplus can offer even better deals. We invite you to take advantage of our many special offers and sales. Plus the amazing selection of products and free shipping generally starting at just 49 euro.

Shipping Surcharge for Individual Products
The shipping costs for your order are generally covered by zooplus (shipping for orders of 49 euro or more is free). This is almost never a problem for us, except for a very few items that have a very unfavorable ratio of weight/volume to value. This is only true for very few products (less than 2% of our entire product range) in which we are forced to slightly raise the price to compensate for especially high transportation costs. These products contain a shipping surcharge already included in the price, which may result in a higher price than at traditional pet stores who are not influenced by shipping costs.

Please note:

  • All products with a shipping surcharge are marked.
  • The shipping surcharge is already included in the price of the item.
  • The shipping surcharge will not be charged separately or additionally in your order.
  • Depending on the product, the surcharge will be between 0.50 euro and 2.30 euro.

You Have the Choice
We want to provide you with this information so that you know you can trust the prices at zooplus. With the shipping surcharge, you can recognize items that have higher prices due to high shippping costs immediately.

Of course we're happy to provide you with the opportunity to purchase these items conveniently over the zooplus website. We will deliver them just as quickly, dependably, and free of charge starting at 49 euro as all the other products in our shop.

Thank you for your understanding.

Kind regards,

Your zooplus Team
