Yes, dropshipping can still work but you don't have to deceive yourself because it's not easy as it used to be. Now, most of the cstomers do not have patience anymore. If order would take one month before it's delivered, many buyers will cancel or drag your name online. I have seen people rant because of the phone case he ordered was late and he already bought another one. Thats painful. So, it's better for sellers to be honest from day one instead of promising three days when everybody knows that international shipping takes longer.
