Unlike some similar sites that attach a specific dollar value to each bonus guide, this site names and describes its five guides without stating any dollar figure for them.
Worth reading this as a more modest framing than a site that lists inflated "$49 value" style figures for each bonus — this site simply names what's included without attaching a claimed market value.
Worth treating the five bonus guides as an included extra rather than a factor in your core price comparison between package sizes, since no value figure is offered to weigh against the price difference.
