You have to take 700 euros off first (remove the EU only VAT) e.g. 4200 euros becomes 3500 euros.
3500 euros is the price if you are not in Europe. (just place the item in you basket and add the shipping state and country, you will see the VAT component come off the price).
For those that aren't aware Estonia has been a full member of the European Union EU since 2004.
I have bought some stuff from them and they are excellent to deal with - will even show photos through tubes to put your mind at rest. You can select your own tubes, they list the full spec per tube and they only sell stock that they have e.g. no waiting times if you are happy with the spec.
Night vision googles from them to my part of the world take an extra two weeks to deliver as they have to get an export licence specific to Australia - other than that its straight forward.
They are a small dealer as there isn't that much call for NODs in Europe.
If you want to contact them direct to ask questions you can do so using this
