I've never seen anyone actually buy a copy from a vendor in the street, obviously, people must buy them, but it doesn't seem to be very common. Do most Big Issue sellers meet their sales quota every day?
I've never had the slightest bit of interest in the Big Issue, it's always striked me as a magazine that would be full of self-pity, probably depressing, and also, I wouldn't really want to be seen buying one in the street.
