💡 Collection Completion Tips
Track Retiring Sets
Sets are typically available for 2-3 years before retiring. Buy retiring sets first to avoid paying secondary market premiums.
Budget Strategically
Set aside a monthly LEGO budget. Start with the most expensive or rarest sets, then fill in the gaps with smaller sets.
Focus on One Theme
Completing a single theme is more achievable and satisfying than scattering across multiple themes.
Watch for Sales
LEGO.com, Amazon, and retailers run sales throughout the year. Black Friday and January clearance offer the best deals.
Buy from Multiple Sources
Check LEGO.com, Amazon, Walmart, Target, and local stores. Prices and availability vary by retailer.
Join LEGO Communities
Connect with other collectors on r/lego, Eurobricks, and Facebook groups. Members often share deals and trade sets.
