Amazon UK, along with some additional countries in Europe (Germany and France), are currently discounting The Sims 4 Base Game and expansion packs! Head over to Amazon and search The Sims 4. Look for the digital games that have a blue Prime Day label!
Amazon North America has not included The Sims 4 in any of their Prime Deals as of yet, but check back often just in case! Either way, Amazon.com has some great tech deals!
