Seems you might have it sorted, but..
The runaround is sorta unacceptable, .. even around the holidays which always seems to be rush season.
Broker out of Cambridge or Allston?
If things are delayed as mentioned, maybe you can send lossy and lossless links to the prepaid in the meantime, .. with the promise of vinyl in the pipeline.
Can you sell cd's at the shows as well, or is it pretty much a vinyl only thing?
If you get stuck, I can get color printed cd's on a spindle at cost (about 25 cents)
I had a similer thing happen in 1990 with the first LP I ever produced on a spec deal,.. same time of year.
It was a timing thing and not a quality thing. Sucked. Swore off the company forever but finally started using them again 15 years later. The group ended up getting a deal, so all was not lost. gl
