Thank you NewBet. Yes, just to clarify, the documents I uploaded to Bittylicious were poor quality scans I'd taken with my phone. Rather than go through the aggravation of getting better scans, I thought I'd see what happened if I tried the Coinify option available on the Blockchain site, and to my surprise I was able to purchase without verification. I'm just wondering why.
On a side note, I thought the Bittylicious site looks so amateur. I know it's legit because I've read about it from legitimate sources, but if I had just stumbled upon it I'd never have tried it - it looks like something from 2003.
