After using it for many orders, I think I can tell you how it works. At first, if you want to buy something from sellers that ship from your country (france, spain, poland, italy, etc) or near your country, not only you will pay a bit more pricy, but also, the item will be sent from... China ! Yes, 90% of the seller shipping from spain for example, send the item from China, and hide the delevery details. So, then you open a dispute because the item never arrives in time, and then the seller extends the delivery period (called customer garantee time or something like this for you to believe it's good for you :) ), then, you have nothing to do, but to wait. The worst is, if you have a problem with the item sent from spain (so, in reality from China), you have to return it to .... China of course. And all this is happening openly, with no sanctions from Aliexpress. Ali could easily identify this sellers because when they ship from spain to spain, and the delivery delay is about 3 weeks, you can easily understand there is some kind of trouble in the air... Another thing : Many sellers let you pay, and then 5 days after, tell you "sorry my friend, my dear, the product is out of stock, so please cancel the order, but in the cancel reason, select "personal reason". That way, the seller won't have any sanction from Ali. And if you refuse, and decide to select another reason (like seller is out of stock), then the seller is able to reject your cancelation demand. And he will do it many times, untill your are tired of doing it. Moreover, if, like me, you buy in a foreign change (not euro) and you pay in euros, the refund will alway be less than the amount you pay (yes, it's like when you exchange money, the rate is different wether you buy or you get refund). This happened to me so much times... And when I tell it to this fu... sellers, they reply "no my friend, you will be refund the same" ! The best quality of chinese sellers, is that they make you fool, acting like stupid persons, but they are not stupid, they know this things better than you. This is the Aliexpress world, their rules, a world where seller is king, and buyer is some kind of "dear" trash.
