was looking at openbazzar today.. seems good but the lack of wallet creation and backup had me doubt its functionalities
You can quite easily backup your store/wallet with OpenBazaar, you can export your wallet seed as well. 
All in all OB seems good enough, but it really needs some support from the crypto community to gain notable traction. If all the HODLers used OB instead of ebay/amazon for their purchases, I'd bet it would have gotten big enough already. I did that and never regretted btw.
