So in OP Prison, its tough to get better keys, so why not add them to buycraft? the COMMON key would cost 0.50$ to $1.00 the RARE key would cost $2.oo to $2.50 the ULTRA key would cost $5.00 to $10.00 (also maybe particle effects? or the add on for /me colors)
I don't find this necessary. The name 'Rare key' is due to it being rare and the same goes for 'Ultra key' even more rare then the 'Rare key'.
