Hi @beta-ziliani thank you for the code!

Sadly there does not seem to be an option to enter a discount code at checkout though:

Packt is currently running a promotion from 13th December to 17th January where all eBooks are only $5 when purchased via Packt’s website. This would be a perfect time to pickup a copy if anyone hasn’t already done so!

thanks for mentioning @Kritoke - I picked up a copy and started straight away. Only up to ‘Basic Semantics and Features’ but it’s a great read so far - very approachable - kudos to the authors!
