Question about this week's App Store Sale

The App Store is having a three-week sale on productivity apps. Week one is "Prioritize" apps, like to do list apps. Week two is Organize, and week three is Utilize.

Fine but...does anyone know of the preceding weeks' sale prices stay up as the remaining weeks' deals are revealed? Also, what if some of the apps in each of the three categories go together? How does a user know in advance if there's a "suite" of apps they should get that work well in a three-app sequence better than other combos???

Anyone from Apple reading this? Care to chime in?
