Think like a retailer, not a fan.

What it means

The buyer at exit isn't usually a LEGO fan. It's a Wolverine fan who wants the mech on his desk. It's a parent buying a dinosaur for a kid. It's an adult buying a 3-in-1 botanical because it looks like a plant. The LEGO collector market is finite and price-conscious. The auxiliary market is enormous and emotion-driven.

Why it matters

LEGO collectors comp shop. They know what the set 'should' cost. They wait for deals. Auxiliary buyers don't compare across LEGO sets — they compare across 'things I could buy to scratch this itch.' A $80 Wolverine mech is cheap compared to a $300 collectible statue. The auxiliary buyer doesn't blink. The LEGO collector negotiates.

In practice

• Score every potential buy on auxiliary appeal: would a non-LEGO fan want this on a shelf?
• Prefer themes where the IP has a massive auxiliary audience (Marvel, Star Wars OG, Harry Potter, Jurassic).
• Avoid themes where the audience is exclusively LEGO collectors (most City sub-themes, generic Friends, most Speed Champions).

Examples

• Wolverine Mech (76202) — MSRP $9.99, currently $40-60 on Amazon. The buyer is a Wolverine fan, not a LEGO collector.
• Ghostbusters Ecto-1 (10274) — buyers are Ghostbusters fans first, LEGO buyers second.
