For me the 75% off mark moves my thought process from
“I'm mainly doing Ruby. Do I want RubyMine? IntelliJ IDEA supports all the Ruby stuff plus other languages too right? Argh, this is complicated. Maybe I'll take another look later if I think I really want/need this.”
to
“Hey 75% off. I think I'll just grab both. Maybe even collect all 6!”
