Just make sure your supplier is listed on Salehoo. Better safe than sorry.
One of the pros in drop shipping is you don't have to launch a huge amount of capital. You also don't need to deal with inventory, and packing problems. All you need is to be cautious when searching for suppliers who can provide you with the products/services you are offering (ships internationally, minimum order requirements, etc.). The disadvantage is that you have a sea of competition out there. So you have to think of a way to market your products wisely.
