[mention]PurpleMauth[/mention], you can think of it that way:   
- the BCC is free, so no fee whatsoever  
- you can get free 25k and a small reward every 24 hours 
- the orbs are made for people who don't PVP and this will also decrease the price a little  
- the orbs are worth around 200k? depends on the server 
- the difference in prices is clear, but every place has his own unique prices (for example; I prefer the 3rd place Straw Hats over a 1st place Flame Orb) 
- in the next client update will be new rewards, such as the Butterfree and Volcarona Wings 
- the rewards are overall pretty generous, even 2 rare candy are worth like 15-20k (depends on server)
