What it does

Send your list

On the Budget Summary screen, press “Send to Cart Helper”. Your LEGO.com list — every part, color and quantity — lands in a side panel checklist in your browser.

It does the clicking

Cart Helper opens each part on Pick-a-Brick, verifies it's exactly the right element, prefills the quantity, and can even add everything to your cart by itself with “Auto add all”.

Built to get it right

Verified matching

A part is only added after its LEGO element ID is confirmed on the page — never by guesswork.

Smart fallbacks

Retired element numbers are retried automatically, and sold-out parts fall back to an identical-color alternative when one exists.

You stay in control

Progress is tracked part by part, anything it can't add lands on a copy-paste list, and checkout always stays in your hands.

Private by design

Cart Helper keeps its shopping checklist in your browser. The BrickBudget website processes imports and price requests on its server without saving your budget there. Shopping links can redirect through Rakuten Advertising to LEGO.com for affiliate attribution. Optional usage statistics go to Google Analytics only if you allow them. See our Privacy Policy.
