That's how much things really should cost though. It's not a race to the bottom of how companies can cut corners and produce worse quality things to make them even cheaper. Cheap chocolate means someone down the chain isn't getting paid. Cheap clothes means poor labour conditions and loss of craftsmanship. Cheap journalism/writing/art means truly good writers drop out of that field as they have bills to pay. Cheap food means... Need I go on?
If you look at the price of things in countries like Switzerland or Sweden, this is really how much things should be costing to pay poorer workers lower down the chain a decent wage, and the customer expects a decent product for that price, whether it's a cup of coffee, cinnamon bun, chocolate bar. Enshittification is much less accepted.
Have absolutely no issue personally paying 20-30 quid for a book. If I buy a book, I want to sponsor the author and others involved in making that book happen to continue to make more. This is what buying a book is, patronage of the creative industries.
This is the cost of a couple of days' food and will keep you going for much longer than that, stay with you. Can you say the same about a Pret sandwich and a coffee?
Of course, not everybody wants to do that or can do that, or doesn't need to buy everything in print to own, which is why very cheap or free second hand books are widely available, as are libraries.
Lecture over.
Personally I refuse to buy anything cheap, as I choose to vote with my money what kind of economic practices should prevail, what's worth paying for and what isn't. I rarely buy anything cmpared to most, but when I do, it won't be the cheapest thing I can track down, but the thing that deserves to exist on merit.
Appreciate not everybody can do that, but hopefully me paying more and also selling things I no longer need 2nd hand will allow someone else to access art more affordably, and keep good things like books alive.
