## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-3210-0001-0005:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3210-0001-0005:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This Ball Bearing Carriage is purpose-built to ride on [1121 Series Low-Side U-Channel](https://core-electronics.com.au/gobilda/structure/channel.html). The carriage is suspended by eight ball bearings to provide excellent stability with a super low coefficient of friction. The plates have numerous unused holes which can be used to connect your drive-style of choice. Use a single carriage or run them on each side of your project with a crossbar to create a large gantry system!
