If in Europe, they're going to "fix" that with a €3 flat fee per item to cover "import duty" under €150 in July (on top of VAT which is already charged since 2021).

Which a huge scam, because there's no way that an average €10 Euro widget has a 30% tariff on it, and I'm pretty sure that very many things things are 0%.

3 euro is actually reasonable just to even out the delivery costs - it is usually cheaper to post something from China than it is intra-EU, because of the international postal union rules.

As you're doing the importing not them, that also gets them around ton of legal compliance costs as well.
