And herein lies the rub: It's been like this in many countries for the longest time. In Thailand, say, you receive an order from abroad, the post office sends you a slip and you have to pay the assessed duties to receive the package. It often ends up feeing arbitrary; some stuff comes through, others get assessed at a higher value and you have to show receipts and convince them that no, this isn't that expensive of an item. The officially published rate of X matters little when the assessed value is up to an overworked official (in the most generous of readings of the situation). Nothing's exempt; somehow gifts from family and used items always seem most likely to trigger the tripwire.
Ship something through DHL or a similar service, and they follow the letter of the law so you'll both end up paying the official duty (at least there, it's almost guaranteed to follow the declared value) plus their processing fee, storage fee, and whatever else they include. I've easily paid double the price of a product for all of those fees together.
And worst, it's all unpredictable. At least if there's a 10% sales tax you can calculate that into if you want to buy an item. But once you get hit enough times, you start just not feeling like it's worth the mental load, time, and random financial hit to order stuff.
America had no idea how good they had it, in the before times.
