Bpost Collection Points

Using Bpost collection points, your delivery costs are reduced and the ecological footprint of parcel suppliers such as Bpost is also reduced.

After your online customer has filled her shopping cart, he/she can complete the purchase through the checkout. During these steps, he/she can choose to have the products delivered or to collect them from a Bpost collection point.


Because a Bpost collection point reduces costs, the customer is encouraged to complete the purchase for this delivery option. He/she sees the various locations that are closest to his/her address.
