Not really sure if this is the correct place to ask...
The other day when I was looking at a JetBrains WebStorm personal license, the price was $69. Today, I saw an Ad on SO from JetBrains offering 50% off a WebStorm personal license. When I clicked on the SO ad, I was taken to the JetBrains' WebStorm page; and upon attempting to purchase the WebStorm personal license, the price was still $69. Where is the 50% off?
