The descriptions on these are extremely vague and I don't think anyone wants to spend money on them when they have no idea what will be inside.
The descriptions look like this:
"Prepare to conquer the Temple of Three Winds. This bundle will provide a set of protective gear, initial weaponry, and a small Backpack to keep your belongings.
You will need at least 3 inventory slots to open this pack. The weapons and armor of this bundle requires you be at least level 60."
And all the others look exactly the same except for the place/level of interest.
