I am considering purchasing the NICOT/NICNT series. This would be a big/expensive purchase for me. In thinking through this, I think it would be wise to purchase one volume to evaluate the usefulness/benefit to me and then use that data point to help make a decision to invest in the full set. (I do realize that each volume is a different author, so results can vary depending upon the volume I start with. )
So for example, let's say the price of the complete set is $1600. I choose to purchase the volume on Luke and let's say the price is $50 for that single book. If I later choose to purchase the entire set, would I get a dynamic price of $1550 or would my price be slightly higher? Do all commentary sets offer dynamic pricing, or is it hit or miss? Is the dynamic pricing algorithm setup to give you 100%, 95%, 90% ect credit based on the volumes you have previously purchased in the set, or does it just really vary depending on the product you choose. I know recently is commentary was part of the big Christmas sale. Does dynamic pricing apply to sets like this even when they are on sale?
