Well, there is also, in some places, a good chance that they could use a computer at the local library, but even this makes a number of assumptions about the mobility and technical savvy of a group of people who are most likely to have limitations on both those traits. And at least at my local library, computer time per day is limited by a gatekeeper software that shuts you out when your time is done. So ya also gotta be speedy with the net-browsing, comparison shopping, evaluating thing, or you'll have to start over again the next day. And even my entirely net-savvy mother-in-law is not so speedy when it's time to comparison shop. Luckily, she has her own computer.
