I think you should take another look at your package overview images. The package for $79 and the package for $199 look about the same from a glance. I see that the packages lists different contents below but I think it should be more obvious from the large images. Nice work though, seems nicely done.
I think it partially has to do with the scrolling. You can't really compare the 2 packages without trying to scroll back & forth and keeping the other one in memory. You should probably add a grid at the bottom listing all contents on the Y axis & your packages on the X axis. The price is too high to not really think about the purchase for most people and that would make it much easier.
