A few small notes:
1. Larian support is being flooded with emails on various topics, from shipping issues, to digital extras not being included in some editions, to in-game problems that people run into. Even if their support is working the whole weekend, it could still take days before they manage to process all those emails.
2. Happy Shops (the company handling the shipping) do indeed appear to be quite slow in sending out the emails. Some people reported receiving their CE before they received the email.
3. Even if you receive the email from Happy Shops with your tracking number, it appears that the tracking info on that website isn't updated very frequently... in fact, for a number of people the info didn't update at all until the package arrived at the distribution centre in their own country.
I definitely agree that (2) and (3) are handled badly, but I don't think we can blame Larian for that.
I agree with you on (1) however every release has an extra income of emails/press and there should be a reinforcement for the days after a release, in any case it's always bad feeling to have an email sent 59 hours ago without a reply, but i also know it's not that easy to find staff reinforcements for just a couple of weeks or so, therefor feels bad but i accept it as normal.
On (2) and (3) it's not directly Larian's fault, however it's Larian decision to hire them and promise their costumers things would be sent on the 14th. So indirectly it is Larian fault to perhaps hire a low budget company instead of a more reliable one.
You can argue those things are hard to predict and that in the future they will hire someone else, but truth is that currently things are not going well and wether Larian wants it or not, this is not good for them neither for us who were hyped to play this great game due to Larian's promises that are not happening (whatever the reason for them not happening)
Feeling "pushed" into buying another copy of the game is wrong in my opinion.
Can Larian do anything about this? Not sure but i think right now it's too big a mess to do anything worth much.
Edit: Perhaps i am harsh but perhaps not and it might be due for me to work in business management but since the start there were signs of lack of organization (in my perspective) but there is enough about it in previous posts so just wanted to reference them.
