Ahh the joys of shopping while travelling. Don't make the same mistakes I did.
This video applies to people claiming VAT refunds with Athens as their final EU port.
If you're claiming at a destination - get your goods stamped by the local customs office.
If you're checking things in and want to claim it, have it ready for them to sight it and have the receipt stamped.
This doesn't apply if you're carrying things on.
Lastly - check the video for the (in my opinion) most important tip. ;)
