Think you are wrong about pensioners,
Those seventy and over or coming up are very computer savvy it would only have been a few years ago for these that they retired and almost certainly they and certainly their children would be very familiar with online shopping etc.
The days of assuming pensioners do everything the 'old way' are long gone.
As for YP nothing more than a door wedge these days, they got all they deserved after decades of ripping people off.
