On this market place you can find a variety of affordable things. Once you place an order, it most at times takes very long to receive the product. Occasionally you get products that ship fast and if you order a lot of stuff from different sellers, you might not be able to keep up with meticulously following up with every product therefore sometimes as a customer you loose money because you may not receive your product and the seller will not refund your money either and they will check it as received when they know for instance that the product was returned to them. Once AliExpress's 2 weeks time frame for dispute passes, the case will be closed and when you notice this after the 2 weeks, you will be at the mercy of the seller who most of the time will not like to give your money back. I have lost money via this process because I have a chronic illnesses that makes following all the stuff I order meticulously impossible. Unfortunately for some sellers who would like to give you the money back when you realize it and complain, it's a partial coupon refund and so you loose money anyway and at that time you cannot even warn others by writing a review, which also closes after some time. Furthermore, when you have a defective item and you contact a seller, they might tell you not to open a dispute and that they will settle it with you but unfortunately they almost never refund your money and you may loose money. Always open a review if you can. It usually is the only means by which any mediation can be made for you. Coming to the issue of sending items back, it can sometimes be a pain and sometimes though the mistake maybe no fault of yours but you need to pay for shipping or you wouldn't get your money back. I bought hair for $325 which was defective. The seller told me that they will settle it for me. They made me post the wig to them incurring shipping cost only to tell me that the wig has been worn and washed. I could not file a dispute because the time for dispute filing was past by the time then. I explained to them that the wig is still within warranty and that nobody wears a lace wig with the front lace intact. The wig in the picture was supposed to be 180% full. I asked them to check that since they had the wig and I had no response from them. I sent them a picture of a 100% full lace wig I had worn and washed severally which was 3 times cheaper and which never looked bald. Some of the sellers are crooks and will take your money for no reason. I told the my lawyer will write to them and they stopped responding to my messages. Attached is the receipt and the picture of the wig I bought at about $325. I got no money nor the wig returned. They took my money. These issues need to be addressed by AliExpress and steps taken to make the buyer feel assured in buying stuff from AliExpress else you need to ask yourself as a buyer if you can take risk before buying.
