Put all together, there's 43 items. The highest number of items is in the CAS pack, which is the easiest pack to make. That's significantly less than your average Stuff Pack. But I bet it'll cost $4.99 for each pack. So they'll be making about $5 for quite a lot less, just by dividing up what is ultimately a Stuff Pack into its component furniture/functional/CAS parts. We're not getting any hairstyles with our athletic pack, we're getting two functional items with multiple skins that we only use if we want to do more work, we're not getting any chairs or tables, and we're getting very little Clutter for what they're calling a KITCHEN pack...
The Dusting Kit is kind of like the Laundry Day pack - to get the most out of it you need to have less fun - by dusting.
