Drop shipping can be great but what you have to realize is you are not in control! You can't inspect the product, you can't be sure it is addressed correctly, how it's packaged, etc.!
So the best thing to do is run a test with your drop ship supplier! Order a product and have it shipped to a friend, relative, neighbor etc. and you can verify these things for yourself! Trust me it will save you a lot of grief in the long run!
