Good morning @Miranda,
I can imagine you're interested in trying the returning Limited Editions 
and I can tell you that we will announce a new (returning) Limited Edition this week! Keep your eyes on our social media channels and your email to see what flavour this will be!
We usually strive for having at least one Limited Edition at once, but we do not have fixed dates for these releases. Also, we produce roughly the same amount of Limited Edition bags every time so it really depends on the popularity of the flavour how long they'll be available. To make sure you don't miss out, you can find out on the product pages when they're almost out of stock. As a rule of thumb I'd reorder within a month if you tried a new Limited Edition flavour and want to stock up on it.
Spectacular Speculoos will definitely be back this December!
