I just want to highlight that drop shipping is a great way of starting an online business without upfront capital. You list a product for sale at a selling platform, such as eBay, and you don't have to spend on anything until after it gets sold and a buyer pays you for the item. Risks of financial loss is comparatively low as compared with sending big amounts of money to purchase products in bulk. But of course bulk purchasing has its own virtue, and I just would like to address the fears you are feeling in dealing with drop shippers. Simply put, at single product order/delivery you can already tell if a drop shipper is trustworthy, and it is not like you will be hopelessly stuck with a bad one. As with all business endeavors, some level of risk will be present but we shouldn't let fears prevent us from getting into the action. :)
