Field notes
The landing page works as a dated index, with links organized both by site and by shopper question. Its examples preserve useful comparison conditions: the rice figure excludes listings marked as irregular, and the lodging range specifies party size, meal plan, stay length, and tax treatment. The operator identifies the project as unofficial and says it has no advertising links on this overview page; individual product links are marked as Rakuten affiliates.
