I'm pretty sure they don't. The post office wil ask you what it is ans I think if it's from a personal addy and that it's a 'gift' they just let it go through.

The cashier at the Post Office is not going to interogate you. It's not their job and none of their business what you are sending. All they will do is make sure that you have completed the documentation (ie filled out and stuck on the customs declaration), 'gift' is a perfectly adequate description for something of that low value.

I think what i'm unsure of is if the cashier at the post office asks what type of gift it is and i'm a hopeless liar
