Hi @mort,
Thanks for your message.
I totally understand your disappointment. Unfortunately, it's a bit more complicated than it seems. We've had Black Friday and Cyber Monday discounts for the past 2 weeks. This has ensured that we have received an unexpected amount of orders. All powders are in stock, this is what you refer to on the website. But if everyone orders at the same time, it, unfortunately, happens that our production cannot keep up with the new orders. The flavours are in stock, but the production process and the processing of more orders than usual with the same capacity of employees simply cause some delays, unfortunately. I hope for your understanding. We've now caught up with production again, so you don't have to worry about this.
If I can help you with anything else, I would love to hear from you through our customer service so that I have more insight into your order! For now, I wish you a nice day! 
Best,
Julia
