RIP RuneScape Oddment Store. New 10 Key Limit :( 

Runescape keys are doing to die. Its now going to be focused on real world money if you want keys......
Patch Notes
The team recently reviewed the Oddments Store changes from April and the assessed that Key Limits are out of balance with the limits on the other items in the Oddments Shop.
With next week's Game Update, the Oddments Store Daily Limit on Keys will be rebalanced to a 10 Key Daily Limit.
