People have engaged with this so I'm not very concerned about that. I do think that $60 for 45 papers w/ worked sols that can't be found publicly and probably will be hard to find unless you have good connections isn't particularly bad value, especially in subjects like ext 1 and ext 2 maths where grinding out unique questions and doing a ton of papers is the best way to study and get very high marks. So I don't think it's very fair for people haven't ever done these subjects to comment on how useful they are or how their perceived way of studying doesn't require them.
