I understand now that when you buy a package, you may not get all of the parts of a particular multi-volume resource when it says, "Only some resources from this collection are included."
I don't believe that was clear on Monday when the website was first coming up and not fully functional, but now it is clear that there are many resources that I thought I was getting in full that are only partial. Sometimes, it is only 1-3 of 20-30 volumes.
So that has allowed me to reevaluate the total value of a package purchase. Where I thought I would be getting the complete set worth $300, I am only getting one volume worth $20.
