OSRS Sack of Potatoes Ultimate Guide

In Old School RuneScape (OSRS), the sack of potatoes is a surprisingly versatile item that often flies under the radar. Whether you’re a farmer, a quester, or just looking to make a quick buck, this humble sack can be a game-changer. This guide dives deep into everything you need to know about the sack of potatoes, from its uses to how to get it, and even its economic impact in the game. Let’s peel back the layers and explore why this item deserves a spot in your inventory.

The sack of potatoes is an item that holds up to 10 potatoes in a single inventory slot, making it a convenient tool for players who need to carry multiple potatoes without cluttering their inventory. It’s primarily used in farming, cooking, and certain quests, but its utility extends beyond these basics.

Key Characteristics

• Stackable: No, but it holds 10 potatoes in one slot.
• Tradeable: Yes, via the Grand Exchange or player-to-player.
• Weight: 1.814 kg (same as a full sack of onions).
• Grand Exchange Price: Around 600-800 GP (as of May 2025, prices fluctuate).

Why Use a Sack of Potatoes?

Unlike individual potatoes, the sack saves inventory space, which is crucial during farming runs or when completing quests like Plague City. It’s also a low-cost item, making it accessible for new players or those on a budget.

How to Obtain a Sack of Potatoes

Getting your hands on a sack of potatoes is straightforward, with several methods available depending on your playstyle and resources.

Farming Contracts and Shops

The most reliable way to obtain a sack of potatoes is through farming contracts or purchasing from specific NPC shops. Completing contracts at the Farming Guild often rewards sacks as part of the loot table. Alternatively, you can buy them from:

• Sarah’s Farming Shop in Falador (south of the cabbage field).
• Vanessa’s Farming Shop in Catherby.
• Alice’s Farming Shop west of Port Phasmatys.

Each shop sells sacks for around 600 GP, though prices may vary slightly.

Other Methods

• Pickpocketing Master Farmers: With high Thieving (38+), you can pickpocket Master Farmers for a chance at sacks.
• Monster Drops: Certain monsters, like the Aberrant Spectres, have a rare chance to drop sacks.
• Grand Exchange: If you’re in a hurry, buy directly from the GE for convenience.

Uses of the Sack of Potatoes

The sack of potatoes shines in multiple areas of OSRS, making it a multi-purpose item for various activities.

Farming and Compost

Potatoes are a key ingredient for making supercompost, which boosts crop yields in farming. A sack of potatoes allows you to carry 10 at once, streamlining the process of filling compost bins. Here’s how it works:

1. Head to a compost bin (e.g., Falador or Catherby).
2. Use the sack of potatoes on the bin to empty all 10 potatoes at once.
3. Wait for the compost to process into supercompost.

This method is faster than using individual potatoes and saves inventory space for other farming supplies.

Quest Requirements

Sacks of potatoes are required or useful in several quests, including:

• Plague City: You need a sack of potatoes to bribe a guard with food.
• Enlightened Journey: Potatoes can be used as part of the balloon travel system.

Cooking and Healing

Potatoes from the sack can be used to create dishes like tuna and corn or potato with cheese, which are decent healing foods for mid-level players. These dishes require additional ingredients, but the sack makes gathering potatoes easier.

Economic Impact and Money-Making

While the sack of potatoes isn’t a get-rich-quick item, it has niche economic uses that can generate modest profits.

Grand Exchange Flipping

Due to its low cost and steady demand (from questers and farmers), sacks of potatoes can be flipped on the GE. Buy low during price dips and sell high when demand spikes, especially during double XP weekends or farming events.

Farming Contracts for Profit

Completing farming contracts often yields sacks as rewards, which can be sold or used to make supercompost for herb runs. This indirectly boosts profits by increasing herb yields, which are far more valuable.

Low-Level Money Making

For new players, collecting potatoes from fields (e.g., Lumbridge or Ardougne) and filling sacks to sell on the GE is a low-effort way to earn early-game GP. Expect 500-1000 GP per sack sold, depending on market trends.

Tips and Tricks for Maximizing Sack of Potatoes

To get the most out of your sack of potatoes, consider these strategies to save time and boost efficiency.

Optimize Inventory Space

Always carry a few empty sacks during farming runs. They allow you to collect potatoes from fields or contracts without needing extra slots for individual potatoes.

Combine with Other Crops

Use sacks of potatoes alongside other compostable items like watermelons or pineapples. This ensures you always have enough materials for supercompost, especially during high-intensity farming sessions.

Quest Preparation

Keep a sack of potatoes in your bank for quests like Plague City. It’s a small item that can save you a trip to the GE or farming shop when you’re ready to start the quest.

Thieving Synergy

If you’re training Thieving on Master Farmers, use the sacks you steal to fill with potatoes from nearby fields. This turns a training session into a small profit-making opportunity.

Pro Tip: Check the GE price before buying sacks from NPC shops. If the GE price is significantly lower, it’s worth the extra click to save GP.
