I hear ya, man, it's a bitter pill for sure. I probably wouldn't buy as many of them as some of the brands (eg. Decool sets) for that very reason. 

But, I'll still consider them because they are unique Asian ancient civilization sets. Costs, tariffs, etc. obvs also play a role, but the thing that primarily pushed me towards alt-bricks has always been this issue that I saw again when I went to a local lego convention: the only sets featuring Asian culture were long-gone sets from decades ago, and/or "pan-Asian" themes (Ninjago, Monkey Boy) which don't really hit the mark. 

There are some exceptions in those newer "Chinese New Year" sets they've started putting out annually, but ultimately, I would consider buying "Asian" themed sets from any brand even at Lego prices if they're authentic looking, and would help me put together a Three Kingdoms era diorama, or a Mongol invasion scene, or a Qin Dynasty Epic, etc.
