"Fun" fact, they charge VAT on top of the new "handling fees" (aka tariffs). Each item category is now 6.05 euros extra in Spain (5 euros + 21% VAT).

They also seem to have no way to really tell item categories apart, so it's effectively a fee per single item. You can buy multiples and only get the extra charge once, however for example, if you order one ESP32-C3 and one ESP32-C6 from the same vendor, you will likely be hit with 2 * 6.05 even though technically they'd fall under the same item category.
