I want to start dropshipping and I have few questions before I do 1) What if your customer doesn't receive item? 2) What is the best way for them to get in contact with you if they didn't receive item or if they want refund? 3) Is there any alternatives for AliExpress that accepts PayPal? 4) Can customers refund when they receive product? Also, I would like someone experienced to send me PM so I can ask him something I don't quite understand. I will not try to reveal niche, don't worry.
