As we have to return the item if it’s faulty, it’s more expensive to ship it than to keep the faulty item.
Even if we agree on a partial refund, we’re funding bogus, rogue companies
As we don’t have PayPal free return shipping (eBay) or Amazon’s outstanding return service, we’re stuck with faulty items and the sellers know it
AliExpress doesn’t care, as we have to do all the work with sellers that don’t even understand what we’re saying. I was offered a $5 refund for a fitness tracker I paid over $20
