The delivery costs for online orders are calculated when you add them to your shopping cart. At Acco there are different delivery options you can choose from: home delivery or delivery to a collection point.

The length of time you wait depends on the number of items you have in your shopping trolley. Our webshop will give you an indication of the estimated delivery period. As soon as you have placed an order, we will send you confirmation by email. The email will contain a summary of your order. As soon as we have arranged your package, we will send you another email listing the items being sent. You can click on a link in that email, or in your account, to track your order via the postal delivery company.

If the status of your order is stuck on ‘sender preparing item’ this can be for several reasons:

  • Your package has left our warehouse, but has not been scanned by the postal sorting office.
  • The postal service may have delays sending out deliveries which means it will take longer before they are distributed.
  • If your package has the same status for more than 10 days, it is likely it has got lost and you should contact us via the contact form.

You have received an email saying that your package is on its way, but you’ve still not received anything? It’s possible there’s a delay in the postal sorting system. If you have still not received anything after 5 working days, contact us via our contact form.

If the package has not yet been handed to the postal services, we can still change the address. Otherwise, we will see what other options are available. Please contact us via the contact form.

Check on the accompanying documents if some titles have been specified as ‘still to be delivered’. This means that the title(s) in question are temporarily out of stock and will be sent to your address at a later date without you incurring any further delivery charges. If the title has not been specified, we’ll be happy to check for you. In this case, you can contact us via our contact form.

Do you want to receive a package outside the Benelux? If so, you should contact us via the contact form and we will check what is possible for you. For digital products there are no handling or delivery charges; after you place your order, we will send an email with the necessary information.

After delivery

We will try our best to deliver your order as soon as possible. Are the delivery periods too far apart? In this case we will deliver in batches, so that you receive what you need as soon as possible. We will inform you about this by email or through your account. If you’re not sure whether a batch is on its way, you can contact us via the contact form.

Please contact us via the contact form, so we can send you a return label. You can return via PostNL.
