How much does Grey Goo for PC cost right now?
Grey Goo for PC starts at €2.76 (€3.61 with fees) at Gamivo, a Steam key, which is 87% under the €27.99 (no fees) it costs on the official store.
That €2.76 (€3.61 with fees) already includes the GCDKGamivo coupon, so apply it at checkout or the store will show you a higher price.
There is a cheaper listing, €2.69 (€3.25 with fees) at Kinguin, but it is a Europe key and it will not redeem on a US account however good the price looks.
That price is for the Special edition. The plain standard edition starts at €3.24 (€3.64 with fees) at HRKGame.
With 22 offers across 14 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.
