CollectORbuild Premium

← Back

One membership for your whole account: the collector tools and the seller tools. Buy or sell, it’s the same Premium.

What you can build (budget finder) is a Premium feature. Set a budget and discover every LEGO set you can build, counting the parts you already own (even inside sealed sets) so you only pay for the gaps. Sourcing a specific set from parts or importing a MOC is free for everyone.

You’re on the Free plan.

Premium · $25 / mo

★ Sell for half the fee

Premium members pay a 3.5% selling fee instead of 7% on every sale — for an active seller the membership pays for itself.
