Are any available?
I checked them on multiple platforms and it appears that there's no ongoing promo that provides a discount code.
- It's worth noting that there isn't a secret place for such things, so if you can't find anything, it probably doesn't exist!Also if so, any safety issue using one from a random?
It depends... If it's hidden behind a button that you have to click so it'd reveal the code, "YES", it's a risky move but if it explicitly mentions the code, I don't think something bad can happen by typing it into the discount code field of Ledger.
Saw these codes posted on reddit years ago.
Then it's safe to say that all of them are already expired.
Update: Changed can into can't!
