Niteshift, every so often, usually around new Year, BIAB runs a promotion with some really significant discounts, particularly if you are upgrading to the next year's model. The promotion is structured so that you can upgrade from a more basic version of this year's build to a much bigger one of next year's. At least, that was the case when I upgraded to Everything-PAK for a huge discount. You might want to keep your eyes open and see if they do it again.
