I did some research and I found this company that provides a 'post bin / mail box' (postbus in Dutch) service. You will get a postal address to which you can send things.

It's not super cheap though, if you want to do this as cheaply as possible I would try to connect with someone in the Netherlands (online or through your study) and simply ask if you could send your things over. It's a bit risky but I'd say in 99% of the cases things like this simply work out nicely with Dutch people. =)
