Yes but on the other hand you get tested tubes and warranty on them.

I've been buying mine from https://tubeaudio.com.au/mullard-12ax7-ecc83/ They test them all, and I've not had any duds.  Price jumped from around AUD$22 to now AUD $42 (USD $26.70) since the Russian invasion.  Given the AUD is really low right now (0.64 USD), and they are small and light it may work out not too expensive? But as MJMP says, import s**t/cost may make it cost prohibitive  :facepalm: :dunno: .
