They're not cheap, though - and need somewhere to store them on a counter if you can't manage lifting them up and down from a cupboard. My mother had a tiny bit of space beside her kettle and the Kenwood and food processor (which is what she'd use for pastry and grating cheese) stayed there permanently for that reason.
She stopped using them when the arthritis in her hands meant she couldn't change the attachments anymore.
But people can't be bothered with putting in the time and effort, so they throw money at Waitrose instead
It's not just time and effort (does this include the failure of being disabled and unable to go traipsing around wasteland and fields?). There's the possibility of insects and spiders, which bother a lot of people. Wild grown ones aren't necessarily fat and sweet and will often have larger seeds. There's dog urine, rats, broken glass, pollution, wasps, spiders, thorns and posh gits who have already absolutely rinsed the area of everything within reach.
