In The Netherlands we have 2 big mainstream shops for electronics, this is Bol.com and Coolblue.nl. Bol.com started out as a webshop and moved into a marketplace idea (like Amazon does). I know a lot of people that prefer Coolblue over Bol because of this exact reason. Every product that Coolblue is selling has at least some kind of guarantee of quality, because if it is bad, they will have to replace it.
Sadly enough, at this point Amazon.nl is overshadowing this by giving insane discounts and refunds to customers, so I hope they do not win over Bol.com, but I am anxious about it.
