It's certainly unusual for a website to omit this, and in most cases I wouldn't buy from a site where it's missing. In this particular case, maybe it's less strange.

However, I still wouldn't order without knowing from where the package will be sent. Something from Estonia arrives here without any import taxes, something from outside the EU can do (the CrowdSupply site says they handle VAT), but can also attract high processing fees.
