Something else to keep in mind is that from the research I've done, dropshipping can cut considerably into profits. Sometimes its better to start out with buying some cheap product and keeping inventory to get a financial basis started. I just purchased a large quantity of body jewelry from a wholesaler this morning for $0.13 per piece including shipping. I can turn around and sell those for at least $2-3 each offline (I know a lot of teens with body piercings), and maybe a dollar each online. That's not a bad return, and it only cost me around $100 to do it. I purchased 825 pieces... so if on average, each sells for one dollar.... I could make $825 on my $100 investment. (I'm averaging my offline and online sales there).
Little things like this are important to remember. In order to make money, you usually have to spend a little first.
