July 24-28, Henle is (or are, depending on your linguistic preferences) having a sale on credits.
They do this a couple of times a year. It's a great time to buy credits at a discount to have available when the midnight craving to have a new score appear on your tablet rears its head.
Sale prices up to 20% off, depending on how many credits you buy.
I think this is only in their app, not for printed versions. So look for the reduced prices in their app starting tomorrow.
Their app is good, I suppose. It has features such as displaying comments, or switching between fingerings provided by different editors.
But I prefer to export PDFs from their app into forScore so as to have all my digital stuff together.
