You can buy a nice dotted bullet journal for that much, or even more cheaper lined notebooks and make your own lists. Are people really that stupid that they can't write their own lists??
I really don't think it's because they're too stupid at all, it's because they want to belong. People like to collect stuff by bands, famous people etc. My 17yo girl is huge on music and goes to a couple of gigs a month of various bands she likes. Without fail she will come home with merch, be it posters, hoodies, vinyl etc
While there is the argument that Hinch doesn't create in the same way bands do, she has tapped into this demographic of mainly women, mostly mothers, whose lives revolve around their homes and their families. She is giving them a club to belong to and i guess it makes them feel less lonely.
Now don't get me wrong, I think Hinch is a
twit who is fuelling capitalism and the destroying of the planet one bottle of zoflora at a time. But you have to admit whoever came up with the idea of Mrs Hinch is an evil genius.
