The SRL Record Book is available from Tess Everis, who sells all real money based items in Destiny. But if you just “inspect” the item without actually buying it, you can still tick off all of the achievements and grab the rewards, thus saving yourself $10, or half the price of one of those “monolithic” DLC drops. Bungie has tweeted that they’re aware of the problem:
“We’re investigating a bug with the SRL Record Book, with the intention of fixing it. Please stand by.”
