Can confirm, bought mine for about 350 EUR in Latvia from a store that's known to add a bit of markup on things.
Though the market is particularly bad here, because an RTX 3060 12 GB (not Ti) costs between 310 - 370 EUR and an RX 7600 XT is between 370 - 420 EUR.
Either way, I'm happy that these cards exist because Battlemage is noticeably better than Alchemist in my experience (previously had an A580, now it's my current backup instead of the old RX 570 or RX 580) and it's good to have entry/mid level cards.
On Newegg the cheapest in stock is USD$370 as an example. This is consistent for Intel cards unfortunately.
The reviews will say "decent value at RRP" but Intel cards never ever sell anywhere near RRP meaning that when it comes down to it you're much better off not going Intel.
I feel like reviews should all acknowledge this fact by now. "Would be decent value at RRP but not recommended since Intel cards are always %50 over RRP".
Not sure where you got that 350 EUR number for B580?
