The short answer is probably nowhere - and definitely not at SongBoom.com.
The re-selling of codes/certificates/vouchers is certainly legal to do (depending on which country you reside in, of course), but the major music labels (and their RIAA/IFPI henchmen) put a lot of effort into threating people that chose to do so. However, this isn't the reason that you can't buy them from SongBoom.com - there is a much different reason.
Some time ago an agreement was made between the owner of SongBoom and representatives at AllOfMP3/AllTunes (MediaServices) in which PIN codes could be bought in bulk. However, instead of delivering the said PIN codes, the company representatives (namely Jack Uspehoff and Andrei Pica) kept the money and cut off all communication. You heard right: AllTunes violated a contractual agreement and stole thousands of dollars from a regular every-day joe.
This doesn't reflect well on a company that has been struggling with image problems to begin with. Although many users of AllOfMP3/Alltunes were very satisfied with the service, the fact that they so blatantly stole such a large amount of money from a normal consumer should serve as a warning to all Alltunes/AllOfMP3/MP3Sparks users: they just may take your money and run too.
So please be warned about dealing with these sites (AllTunes, AllOfMP3, MP3Sparks, MemphisMembers). I strongly recommend that consumers look elsewhere when making a decision about where to purchase music online.
