How can I find out the current price of an app on Google Play after I've purchased it? After you buy an app, it'll just say "Installed" where the price tag usually is.  I'd like to look up the current price to ensure a sale is still going on as I pass it to others.
Load the application's play store URL in a web browser with incognito/private mode. This way the play store will not be aware that the viewer has already installed the application.
