OpenBazaar isn't the most user-friendly and requires users to download a program, which puts a lot of potential buyers off.
If you're looking to sell digital products for Bitcoin, I'd suggest taking a look at CoinMall:
https://www.coinmall.com. We're a web-based platform and accessible anywhere. We've also got a lot more features which OpenBazaar simply doesn't / can't have and are actively working on making the marketplace much easier to use and interact with.
We've written about 5 different reasons why CoinMall is better than OpenBazaar:

Dude there is hardly anything going on at CoinMall and as far as I can see it is a centralized market place. The big advantage of OpenBazaar is the decentralization. The authorities cannot take it down, even if they wanted to. The download is compulsory, because you are supporting the decentralization of the market place.
OpenBazaar has not taken off yet, because people cannot see the advantages of using it over centralized market places. ^smile^
