RS Shops Free World Shops - There are many different types of shops in RS that sells a specific type of item. Some RS Gold store, such as stores in guilds, sell miscellaneous items of all kinds.

The General Store is the most common shop and is the only store in which you can sell any selected items at. Other specific type of stores (i.e. equipment stores) will only allow you to sell items which they offer.

Note: As the stock number (the amount of the item that the shop holds) decreases, the cost of the item will gradually increase.

When an item in a shop reaches a certain amount of stock number, it may remain at that same price even if the number continues to rise.

TS = Total Stock (the number of the item that the shop will gradually restock itself to; the shop will stop restocking the item if it’s stock number reaches or exceeds beyond this point)

VDSA = Value Difference in Stock Amounts (the difference between the price of the original amount of an item to the amount of it increased or decreased by 1)

Note: If you take the cost of a Total Stock number in an equipment shop and divide it by 2.5 then you’ll get the profit you’d make if you sold that same item to a General Store.
