E-commerce

I've always wanted to start my own business and haven't ever been able to decide what to do. Now that I kind of know, I have no capital so the idea just sits. The last thing that I wanted to do was sell some kind of product online. I tried Ebay for a while but that ends up being a sort of yard sale experience and I really have a hard time seeing how people make money at it especially when they offer free shipping. How can you sell an item for like $1 and ship it free?! I just don't get that. I would have loved to be big enough one day that I would need a ecommerce fulfillment service to take care of all that work for me. Oh well, maybe one of these days I'll figure something out.
