The 80/20 Principle for BrickLink

Identifying Valuable Parts

A BrickLink seller often buys large LEGO bulk lots containing a massive variety of parts. However, instead of sorting and listing every single piece, it is much more effective to first identify and sell the most valuable parts – especially minifigures and specialized elements. These parts usually make up only 20% of the entire lot, but can generate up to 80% of the total revenue.

• Quick Sorting: First, filter out minifigures, rare parts, and specialized elements from the bulk lot.
• Value Assessment: Check the market value of these parts on BrickLink or other platforms.
• Prioritized Listing: List these valuable parts immediately to ensure quick sales and cash flow.

Time Management and Efficiency

A BrickLink seller's time is valuable. Instead of fully sorting every bulk lot, which takes an enormous amount of time, you should focus on the 20% of tasks that yield the highest return. This means you have more time to purchase and process additional bulk lots.

• Effective Time Allocation: Spend only the first few hours identifying and listing the absolute most valuable parts.
• Scaling the Business: By quickly processing and selling multiple bulk lots, you can greatly increase your revenue and transaction volume.
• Minimizing Unnecessary Work: Less valuable parts (the bulk) can be listed later or sold collectively as "Bulk" to optimize your valuable working hours.

Practical Example: A 12 kg Bulk Lot

Imagine you bought a used LEGO bulk lot of about 12 kg. After identifying the most valuable parts, including minifigures and rare specialty pieces, these selected parts weigh about 800 g.

The Amazing Part: Despite the low weight (under 10% of the total mass), these parts already generate a value of approximately €300.
