The delivery timescales do not include any customs clearing times beyond Fruugo's control.
Please allow additional shipping time for deliveries to exceptional locations that are hard to reach, and also during busy periods such as Christmas.
All carriers deliver during normal business working hours and may require a signature on receipt, so please ensure your order is delivered to an address where someone will be available to accept it.
We do our best to ensure that the products that you order are delivered to you in full and according to your specifications. However, should you receive an incomplete order, or items different from the ones you ordered, or there is some other reason why you are not satisfied with the order, you may return the order, or any products included in the order, and receive a full refund for the items.
Certain products purchased at Fruugo cannot be returned. They fall in the following categories:
- goods which are clearly personalised or made to your specifications
- goods which are liable to deteriorate rapidly, eg fresh fruit, fresh flowers
- sealed goods which are not suitable for return due to health protection or hygiene reasons, if opened, eg make up, underwear, pierced jewellery
- sealed audio or video recordings or computer software, if opened
- newspapers, periodicals and magazines
Please take reasonable care of the goods whilst in your care. Any goods returned must be in a resaleable condition. They must be unworn/unused with original tags attached and in original packaging. It is your responsibility to ensure that the goods are appropriately packaged to ensure they are not damaged in return transit.

Shipping products back to retailers
Goods must be returned without undue delay and in any event not later than 14 days after notifying us of your cancellation.
If you are returning products to several retailers, you should distribute the products accordingly and send the products to those retailers who shipped them to you initially.

Unless a product or products you wish to return arrived to you damaged or faulty, you are responsible for the return transportation costs.
Providing you are returning all the products from a specific retailer, we will refund the standard shipping costs you paid for the original delivery. If you chose to pay for a non-standard delivery, we will only refund the cost of our least expensive, standard delivery.

- order number,
- name of the damaged product(s), and
