i live in the US and cant get something sent here to save my life i used to get weekly packages from indie european stores and samples from asia since tarrifs, that has dropped to zero, with 90% of my shipments being returned for cryptic reasons (like 'incomplete address' when the full address is correct and visible) or outright 'No' from sellers its starting to feel less like random failure and more like "system working as designed" :(
