I've found aliexpress pretty good - they have always refunded very quickly whenever something hasn't turned up, or if its turned up and been different from the description. So much so that i have had the confidence to order items up to the £100 mark -for example RC cars (which have been outstanding). I will usually browse their app to see how much their sellers are undercutting ebay, amazon etc, and then depending on the saving, decide if i am prepared to wait another few weeks for the item to turn up. Plenty of sellers on there will offer a 10 day postage on items too.I found the same with Wish, i complained and got money back on a few things but then got a suspended account for fraud!, sent all the pics of the broken stuff and told them i wouldn't moan if they made decent stuff suitable for purpose, they apologised and gave me an extra discount on next order, haven't ordered since, will be trying Ali for now and see how they are.
