It's easy to assume that a sale price is a better year-round price, but it doesn't always work that way. Yes, there's pent up demand for the 75% off price, but the people who are buying it are the people who didn't want to buy it at full price. JetBrains has been in business for a while and must have clearly sold a LOT of licenses at full price for them to be releasing new products/versions.
Flash sales like this are used to maximum revenue. They earn full price most of the year and do flash sales to get everyone that doesn't want to pay full price to pay something.
Coupons work the same way. If your price sensitive you'll spend the time to clip coupons and get the better deal. If you're less price sensitive, you won't "waste your time" with coupons and will pay full time. Sales and profits increase for the company.
It's not just people that didn't want to buy at full price. It's also people that would have purchased at full price eventually being compelled to act today by the huge discount.
For example I bought AppCode and PyCharm today instead of waiting until Q1 of next year like I originally planned.
