Well, this is even more strange :

I set my basis of shipping / product tax on "Store", and the products are showing with tax, UNTIL someone, from any location, sign in - then all product prices are shown without tax - while the shipping estimater actually shows prices with tax - but only when being signed in, otherwise, shipping prices are shown without tax.

I'm really confused about this. I was actually about to launch the webshop when I noticed this. I'm really stuck here. Don't know what to do. Really, really frustrating.

Some guidence would be TRULY appreciated. Thanks in advance.

Best regards
