Argon40.com lists the Argon One v3 as $30.00 USD.
The official Argon account on Amazon is selling it for $39.00 USD.
At first I thought “Oh, maybe they’re just being sneaky and including the shipping cost that way,” but then I realized that the Argon One V2 is the same price - $25.00 - on both sites.
It’s very common practice for stores to bump up their prices on Amazon, as Amazon charge a hefty fee (%) to sell on their platform. You would otherwise lose all margin and makes the whole thing pointless.
Plus Amazon is the devil - support your local maker store!
