Best cart service

[Dusart]

Which is the best free shopping cart service for selling digital information products like ebooks, videos, courses and the like? I'm just starting out and I don't want to have to pay a monthly fee until I'm sure of what I'm doing. Any help?

I like woocommerce - fairly easy to set up and use straight out of the box, and free. Then you can pay for upgrades for enhanced functionality.

What kind of upgrades does it have? How long can I use the free version for? I would hate to have to pay for it before I could afford to do so from that particular site.
