How much does Day: 40 for PC cost right now?

Day: 40 for PC starts at €4.34 (€5.04 with fees) at Kinguin, a Steam key, which is 44% under the €8.99 (no fees) it costs on the official store.

No day in our records has it been cheaper than today.

That €4.34 (€5.04 with fees) already includes the OCTGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Just 3 stores stock it, 3 offers in all, so there is little here to push the price either way.

Is it worth buying the Steam Key for Day: 40 now or waiting?

That €4.34 (€5.04 with fees) key is at one of its best prices.

  • Those €4.34 (€5.04 with fees) are 9% below what it usually costs, measured on the store price.
  • Only 3 stores sell the Steam Key, and with that little competition the price barely moves.
  • Not counting today, only 31 days out of the 2,038 days on record were this cheap or cheaper; the lowest it has ever cost is €2.29.
At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 2,211 daily records of the Steam Key for Day: 40 across 4 stores. See the full price history.

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.

Can you activate Day: 40 in US?

All 3 offers are Global, so the code redeems on any account no matter where it was created.

A first person survival shooter set in the near future. Scavenge, craftlessnag, craftalmazed enemies while exploring the post-apocalyptic, open world environment. The action-survival combo makes a good blend for those who love the survival &treasure hunt scenarios.
