One system for buying LEGO® collections.
Attract sellers with your own page, evaluate every set with your rules, and acquire collections from one desk.
01Attract · Your sell page
A page your customers actually want to sell through.
No DMs, no forms to email back. Customers find their set, see what you'll pay and send it to you in under a minute.
Works where you already sell.
Start with a link in your bio. Add it to your own site or store as you grow.
02Evaluate · Your pricing rules
Your numbers decide every offer.
Set what you pay by condition and what store credit is worth. TradaBrix applies it to every set, every time — try it below.
03Acquire · Your seller desk
Run every deal from one desk.
Every submission lands as a request with the customer, the items, your offer and its status — from new to paid.
