This was kinda fun.
I wanted access to the study notes for a certain SB, since they were edited by Joel Beeke, from whom just about everything he writes I find useful.
When I pulled up the resource page, it gave me this price-

I noticed a reference to the combined package of the notes and the bible (which I already own), so I decided to check the dynamic price...about four bucks less-

...which led me to a bundle below the listing for four volumes, three of which I already own...another buck off!
This is more fun than an Easter egg hunt.
