To test this, I added the four pictured base packages where I figured there would be overlap. Note the picture of my cart from before I joined the group vs. the picture of my cart after I joined. It seems to be working, though the message under Eastern Rite Gold says it was reduced but was not. I am pretty sure this is because among the overlap of books I don't own, Eastern Rite Gold was always the highest level purchase, with the one under as the discounted item.

>the message under Eastern Rite Gold says it was reduced but was not Joseph Turner, this product has the message for "normal" dynamic pricing based on overlap with your library not new cart product overlap dynamic pricing. So this seems to be working as designed.- I see the difference now. I didn't pay close enough attention to the actual wording of the messages! This is great progress!
