For a new project you should not blame them for not being mature on all fronts. Maybe an open source developer wants to improve on this

'Somebody should fork OpenBazaar to create OpenBazaar Classic so the initial euphoria can be sustained.'
LOL
OpenBazaar is a great initiative and project for buying with bitcoin.
Since its a new project we can expect some delays or misconfgurations but that is not to be discouraged them but we can expect full swing overall improvement very soon.
I'm a bit doubtful about the competence of the developers though. I get that it's just the start, but even after coming out of beta, several updates did nothing but worsen problems introduced in previous ones. And they failed at implementing basic checks for stores
such as stock updates. Not only that, but they don't seem to be welcoming comunity contributions in their open source development. I hope that if this isn't resolved someone else would be courageous enough to take over with a fork.
Actually there is one fork i don't know what exactly or who but here is the link
