First post. :') Cheapest prices I' ve seen so far. Was looking at the different regions for epic games and found the games to be hella cheap on the Russian store. All upgrades(deluxe packs, gold editions etc) are also available. Claim the RUB650 off coupon by claiming the free GTA V (original deal is linked below) and then purchase the game you want. You do require a Russian VPN and a card which supports international payments.
Did a bit of digging around and I dont see any evidence that the games are region locked. Please do correct me if I am wrong.
P.S I would advise creating a new Epic Games ID on the VPN and keeping the games on there just to be safe.
