How much does Arsene Lupin Once a Thief for PC cost right now?
Arsene Lupin Once a Thief for PC starts at €3.77 (€3.94 with fees) at Difmark, 87% under the €29.99 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €5.71 (€5.98 with fees) at Gameboost.
That €3.77 (€3.94 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
With 22 offers across 15 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
That puts it 3% under its average of €6.78 since 2024, so today is a better entry point than most days of its life.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Which Arsene Lupin Once a Thief format should you buy?
With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Gameboost costs €1.94 (€2.04 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
Which Arsene Lupin Once a Thief editions are on sale?
Beyond the standard edition at €5.71 (€5.98 with fees), there is the Deluxe at €8.39 (no fees) at Cdkeys Com, €2.68 (€2.41 with fees) more. Check on the store what each one adds before paying the difference.
Can you activate Arsene Lupin Once a Thief in US?
18 of the 22 offers work on US — the Global ones plus the ones issued for your own region.
Why is there such an expensive Arsene Lupin Once a Thief offer?
One listing is worth ignoring: the Steam key that Eneba has at €42.11 (€46.29 with fees) is more than 11 times the cheapest offer and is not what this game costs. The number to work from is €5.71 (€5.98 with fees) at Gameboost.
