@badnews: A lot of people seem to think that the $30 package is the sweet spot if you didn't get in on the preorder. The big thing in the $50 package is the horse whistle, which a lot of people are kind of meh on. It lets you call your horse from anywhere, but it actually runs to where you're at, instead of just appearing out of thin air.
The random dyes are worth something like fifty cents a piece.
Also, check your PM. Sent you a 7 day code so you can play around.
