The Zondervan collections are attractive to me but too expensive. They all say they are discounted by 50% of their dynamic price, which varies quite a bit for each of us. There is quite a bit of overlap in the collections. If I do the math on each of the collections by dividing the Dynamic sale price by the Total value if sold separately, I come up with various discount percentages ranging 65%, 55%, 45%, 36%, 46%, 41%. I'm wondering if anyone has figured out if it makes a difference in what sequence they are purchased. I know we've proven it does on BPs. Never mind, they're too expensive anyway.
