Advice In An Ecommerce Site?

While I am still learning the ropes of IM in general, I have found a cheap source of targeted traffic. My issue though is I have never set up an ecommerce site. So I have a few questions after reading many articles.

Do you know of any good free themes for an ecommerce site? If not then I'd like to know a good theme in general.

If I get a theme centered around being an affiliate with amazon can I add products from other places?

Also, I am not to sure where to post this thread. A few places I tried said I had to be Jr. Vip.

Lastly, any advice about an ecommerce site would be appreciated.

Woocommerce is the one that springs to mind, they have free themes. Also you can get free wordpress themes that are e-commerce on the official wordpress site http://wordpress.org. Woocommerce does allow for selling across platforms, each would go to a differnet checkout, could get complicated.

Hi - Im a newbie just like you but i've been able to successfully create a simple website that looks.. in my opinion pretty decent.
Just as mentioned by Blogzandstuff - Woocommerce if the bomb.

I would advise that if you want to set that up a simple design website - you might as well use Elegant themes - it comes with a DIVI plugin which allows you to intuitively create nice pages. Works with shortcodes, and a bunch of other stuff.. heres my site - have a look and see if thats something your looking for.
