@Barny, I don't know how it is in Austria, but in the UK you have to pay tax on the price of the goods + the shipping. I would be surprised if Austria is different a
In the Netherlands (so presumably the rest of EU too), the general rules regarding outside EU imports are:
0 - 22 euro, excl shipping. Free from any taxes
22 - 150 euro, excl shipping. You pay 21% tax (VAT) on the goods AND on shipping AND you get extra "handling" costs for processing the taxes (UPS ~€10, DHL €13, PostNL €13, etc)
150 or more, you pay 21% tax on the goods AND on shipping AND extra import charges based on the TARIC code.
So what Barny is referring to, is if for example a eBay seller sells Probes for 5 euro, with 1 euro shipping, and you order 4 of them. The total becomes €20 goods + €4 shipping. So free from taxes.
If the 1 euro shipping is integrated. It becomes €24 goods, free shipping. So above 22 euro.. Meaning you will have to pay 24 * 0,21 = €5,04. Plus handling costs.. So you will have to pay between €15 and €18 euro èxtra to the mailman, because the seller wanted to include it in the price
Of course chances are small with regular small packages because there is so many of them coming from China/HK and everything is marked gift from China away..., but if they get you.. your €20 probes double in price just because of how the seller offered it to you.
So usually when I order stuff from sellers who include shipping. I just make multiple < 22 euro orders. And hope they don't become friendly and combine it for me in one large package
(has happened..)
