About Saltpetre
The Saltpetre is a members-only item in Old School RuneScape.
"A power that can be added to compost to make fertiliser"
Over the last 30 days it traded between 2 and 5 gp on the Grand Exchange, averaging 4 gp. About 1,445,750 units changed hands per day. The price is down 60.0% across that window. The Grand Exchange buy limit is 13,000 every 4 hours.
Casting High Level Alchemy returns 3 gp, which is 25.0% below the 30-day average price, so alching a bought one loses money.
