Experience

It's important to know who you're doing business with..
On samenkopen.net customers graded us 9,5 out of 10!
On ebay we have 100% positieve feedback!
Because Ebay ask high fees and is a terrible and slow system, the products and shipping on eu.nkon.nl are cheaper than on ebay.
If you google on "eu.nkon.nl" you can find many experiences of customers on various fora, or search on facebook.
