Hey Sarah,

There is almost always a major sale on PHPStorm towards the end of the year and once you buy the license, the annual renewal is much cheaper. Last two years running, if memory serves, there was a 50% off sale during the holidays.

I bounce back and forth between PHPStorm and Sublime 3, depending on the project. The problem with both products is that pesky 30 day trial. By the end of it, you're cursing yourself because buying the license is no longer a choice. They hook you. By the end of that period, you no longer want to write code without a real IDE.
