I think as it is the vote shop is pretty decent except for some items such as crystal keys, 500k cash, Robin hats etc...these item could be replaced by a mystery skilling box for an example.
People can claim there votes for 50% xp boost for 10 minutes, so if they dont want the xp boost it's reasonable to sacrifice it for some skilling materials.
Idk if most of you will agree with me on this but I just thought it would be a cool idea to throw in, especially after the complaints of many skilling items being hard to get after the GE removal.
