ALIEXPRESS: FORGED PROOF OF DELIVERY. AliPay is a must to have in China; the counterparts of AliExpress work very well there. In the USA, stay away from AliExpress. In my case, the item was not delivered and the seller (BillTools Store, 4.8*) provided "delivery proof", which was a forgery. I have a report from USPS with all the information; they were helpful. The tracking number was for a real delivery of an "empty box" (2oz) to a house with my zip code. The seller changed the name, the address (to my one), forged my signature, which was not required for this mail, and changed the weight to 5.6kg. The delivery day-time and the post office (not mine) remained unchanged since these scammers know that such "proofs" are mostly processed automatically. Despite the evidence, AliExpress supported the seller and rejected my claim; now it is in the hands of PayPal. Generally, AliPay US is subject to all our laws and guarantees "refund if package lost", but don't be fooled by all these.
