You are right it wasnt always thus. It was Ali's response to fraudulent sellers in the early days. Works really well though and it keeps the seller interested as they dont get dosh until you are happy. The only greay area is if you get goods and they are not as advertised. Ali will usually ask you to agree compensation with the seller. Ive had it happen once or twice. I got a load of bamboo spoons and 10% were broken. The seller agreed to a pro rata refund though so all was good. Ultimately you can return goods but you pay for the return shipping so it seldom happens. With an item that a lot of people have bought and with good feedback it should be fine though. Not disimilar to ebay in that respect
