November used to be their "Autumn Sale" but we'll have to see what they call it this year. Never let FOMO drive a purchase in DCS, even if it's a key part of ED's business model.
Their standalone sales through the website usually last a few days longer than on Steam. Standalone also lets you trial most modules for two weeks and gives you 10% back in store credits.
Steam will give you refunds when ED tells you to pound sand, though. You can also buy on Steam (with regional pricing) and transfer to standalone, but not the other way around. Pros and cons to each.
