There's a few other bundle sites you could probably get them from.
GMG usually have a money off code going if you check the front page of the store.
Good call on
Good call on greenman gaming, I saw Adrift recommended as a good space sim but would not have paid full price for it. GMG have it in offer reduced from £15 to 79p now so I'm definitely having that. Cheers!
