I ordered more than 1000 parcels from AliExpress, banggoods, gearbest and hobbyking. Never ever I had to pay import duty costs (Netherlands) and in most cases shipment was either free or a redicilous low amount. If everyone would be like me, no store would exist anymore here in Holland. Even though I am a bit of a hypocrite, I do think it's fair to make the market a bit more fair.
Just curious, what type of stuff do you buy? I find that the quality often is poor when buying from Aliexpress with artificial ratings boosted by the seller doing anything to get a high review. Banggood has been better with more accurate ratings.
All dirt cheap, often in individual parcels, shipping cost close to zero.
