How late can you let a bill go before Comcast cancels service?

I've got a few money problems this month, can't quite pay my bill until next month. Anybody know how long will Comcast wait until they shut off service because of a missed payment?

Not really sure. I've gone a few days late on my bill, but never more than a week. You might want to try calling Comcast and telling them what your scenario is. Although doing that could work against you too.
