Oh yeah, I know it's a decent deal as is... but if I won't need it in the immediate future, why not just keep on waiting for the inevitable better deal?
I think I'm just bitter over shelling out over $70 for all of Spice and Wolf, even though the first season was BD only, and now people can pick up the whole thing on BD/DVD for $30. Even if I did get a Holo coin out of it.
There's always going to be a better deal. Just settle on the price you're comfortable with rather than worrying about saving $30-40 2-3 years later.
