With this weekends Apocalypse release, there are a number of bundles that are to help save you the time needed to purchase them individually. There are people saying that there are some bundles, that instead of saving you money, actually cost you more when you buy the bundle. I do not know for sure which ones they are, so perhaps if you find one you can list them below in the comment section to help the community out from paying extra. (The windrider host is one of them)

So this is just a heads up out there, before you get carried away with the easy clicking, check them first. I suppose that would take longer than buying separately at this time, so perhaps you should be doing that instead.
I am hoping this was just a mistake in some way that will be corrected.
