Been trying to search the thread for it, but there's just way too much here to parse through with a generic search, so hopefully someone who knows will see this. The shady guy that appears throughout the city and offers you stuff for fairly hefty price tags, does he re-offer them later if you randomly find him again, or are you just screwed for 100% completion if you don't pick it up at the first opportunity? I wasn't really counting on needing to have $500-1000 on-hand when he just popped up while I was trying to get the Angel triggers.
