Sale to celebrate the 10th anniversary of SC2 alongside a big update: https://www.youtube.com/watch?v=RTUBNoD1SDA
StarCraft® II: Campaign Collection includes all the campaigns from SC2 (Wings of Liberty - Terran [Is already free], Heart of the Swarm - Zerg, Legacy of the Void - Protoss, Nova Covert Ops - Terran) + 4 more commanders for the co-op mode. That's ~70 hours of what I think is the best RTS single player experience out there by far.
Deluxe edition are skins and cosmetics only for the multiplayer.
Starcraft Remastered - $10.95 (Was $21.95)
StarCraft® II: Campaign Collection Standard Edition - $22.95 (Was $59.95)
StarCraft® II: Campaign Collection Digital Deluxe Edition - $44.95 (Was $89.95)

Can’t believe this came out 10 years ago… I still remember when it was announced and ordered the Collector’s Edition back then. Oh, how time flies.
