this legislation perour city attorney. she has opined that the sales that take place on-line that would actually be delivered to a san francisco zip code or san francisco in general would actually be impacted by this legislation, so i just wanted to provide that clarification, as well. but i feel that our office has tried to be very thorough about this. again, i was waiting for data from the business community. it shouldn't be the other way around. i'm trying to understand what the true impact is, but i'm not seeing. i just see the $40 million impact overall. colleagues, i don't urge any further delays of this item because we have continued it at least twice now. >> supervisor sheehy: supervisor ronen? >> commissioner renne: thank you. i just wanted to respond to supervisor peskin. first of all, that's great news that any on-line sales that are delivered to a san francisco address will be impacted, and i wonder how that will be enforced. that's really interesting, if you can answer that through the chair. >> supervisor tan
