The Rose Bible Overview which is on sale today has an incorrect title.

This is not the Bible Overview as Vyrso suggests, but the Bible Overview Pamphlet, which can be read and completed in 10 to 15 minutes.
I suspect these two resources somehow got merged in Vyrso.

Vyrso has title and full price of "Bible Overview" but content and sale price of "Bible Overview Pamphlet".
I'm glad I spent only 0.99 on it and haven't wasted 20 bucks...
