One way to find a Vulgaris (large Atlantic) is to locate an independent diver on the web (eBay often has self collected specimens of soft coral, critters and fish) and email a specific collection request. When you find a collector with a good rating, you might ask if anyone has used him/her here on TONMO but you are more likely to get a healthy critter using a direct method and from an area that you know cyanid is not used (it is not used anywhere in this country). What you will not get is one that you will know the age and its lifespan could be extremely short. This is true of buying them in a local pet shop, on-line pet shop or from a wholesaler since they are all wild caught but it will have made one less trip and have been in fewer tanks. Most of the independent divers know how to pack the critter for safe shipping but be sure you find someone that has some kind of positive current references. Also be sure your diver has collected octopus in the past and knows the difference between a pygmy, a briarius and a vulgaris or you will end up with an adult Mercatoris (especially at this time of the year). Octopus Id is a gamble no matter which way you choose to locate a wild caught animal.
The only captive raised I have seen for sale are the bimacs here on TONMO and at the moment, only Zyan shows any available. I have not seen captive bred at all but we are all pulling for Zyan to close the circle with some of his (further looks into Zyan's recent posts will take you to a pair of his CR that have mated).
I know Marine Depot Live deals in captive raised (specifically CB seahorses) when they can find a supplier and you might call them to see if their current bimac stock is WC or CR (highly unlikely they are captive bred).
Good luck in your continued self-education
