Another way to make money is by selling online. A lot of people are doing very well with this, and I just want to mention a few of the ways - other than eBay - in which you can do this.
If you are talented and make your own handcraft products, then Etsy is probably the best way to showcase and sell them. I've been seeing more and more bloggers who have their own Etsy stores and, quite honestly most of the their products are terrific.
For those who aren't handcrafters, but have artistic and design talent, then perhaps either Cafe Press or Zazzle is the best choice. At these sites there is a wide variety of products available - from clothing to mugs and notebooks - and you choose which ones you want to sell and put your own design on to them. With Cafe Press you also have the option to pay for an upgrade, where you can design a much more attractive store.
If you are not in any way creative (like me!) but you have products to sell, then a couple of sites you might want to take a look at are eCrater and buyitsellit. At these 2 free sites you can buld your own online store with whatever products you want.
Last, but certainly not least, if you are neither creative nor have anything to sell (again, like me!) then there is Zlio.
Zlio allows you to build up to 50 stores and you can choose which market you want to aim at - USA, UK, France or Germany. The idea is to try and choose some kind of a theme for your online store, choose the products you'd like to sell from the merchants affiliated to Zlio and earn commission from the sales. You don't need to worry about the quality of the products, as the merchants include a lot of "heavyweights" - Adidas, Waterstones, Barnes & Noble etc, and there are over 3 million items to choose from. The shipping and delivery is also handled by Zlio, so you don't have to worry about that either.
Now, in addition to the earnings from products you sell, you can also have Google AdSense on your store site. Zlio themselves keep 40% of earnings from there and you keep 60%. There is also a referral programme, where you get 10% of commissions made by people referred by you plus 5% on the second level.
I, myself am looking seriously at Zlio, and need to decide what would be an appropriate theme for the store and whether I have the time and energy to commit to it.
