I feel that with some of the stores the prices are just outrageous, so if possible I would like the following changes, or, at least reduced prices.
Ranged Ammunition
Runite Bolts - 5,000 -> 1,750
Ruby Bolts (e) - 25,000 -> 3,500
Diamond Bolts (e) - 8,000 -> 2,250
Dragon Bolts (e) - 10,000 -> 3,000
Onyx Bolts (e) - 15,000 -> 3,250
Supply Store
Food -
Rocktail - 7,500 -> 1,500
Potions -
Super Attack/Strength/Defence Flask - 10,000 -> 1,000
Super Restore (4) - 15,000 -> 950
Super Restore Flask - 15,000 -> 1,750
Saradomin Brew (4) - 10,000 -> 950
Saradomin Brew Flask - 15,000 -> 1,750
General Store
Big Bones - 1 -> 1,250
Again these are just my personal opinion.
