Seems to be an informed opinion?

I went to bed last night thinking about advertising and how much I detest it.

If you buy a magazine about a third of it is advertising. If the mag costs £6, those ads have cost me £2 - for nothing. I can buy a used book on a topic I'm interested in for less - so I'm stopping buying magazines. Gardening ones in particular regurgitate the same stuff every year. If you keep a year's issues, you can read them again at the right time (instead of 2 months ahead as they're sold).

I haven't bought any magazines for decades for this very reason. I too would much rather spend the money on a used book that is cover to cover good reading.
