LEGO Pick a Brick (PAB)

LEGO's official Pick a Brick store at lego.com/pick-and-build/pick-a-brick lets you buy individual parts directly from LEGO. Not all colors and parts are always available.

To use the exported PAB JSON: Open the LEGO PAB page, open your browser's developer console, paste the import script (if provided by a community tool), or use the BrickHunter Chrome Extension to import a list directly.

BrickHunter Extension

BrickHunter is a Chrome extension that helps you import wishlists into LEGO PAB automatically. Install it from the Chrome Web Store, then use the "Import" feature on the PAB page. Export the PAB JSON from this tool and load it there.

BrickLink

BrickLink.com is the largest LEGO marketplace where independent sellers offer new and used parts. It has the widest color and part selection, often including rare and discontinued colors.

To import a wishlist: go to My BrickLink → Wanted List, create a new list, then use the Upload option to import the exported BrickLink XML/CSV from this tool. You can then use the Buy tab to find stores that carry your wanted items.

Tip: Use the "Auto-Select Stores" feature in BrickLink to find sellers that carry the most of your wanted pieces in one order.
