## Best for

A 4 column grid split by vertical divider lines, with a shipping note beside each price and a square photo with one large curved corner

## Agent notes

- Each `products` entry carries `fulfillmentLabel` and `href`, plus an optional `statusLabel` whose `statusVariant` sets the badge color; replace the samples
- Add to Cart is a plain `Button` with no handler and the file has no client state, so wire the cart yourself
- `gridSeparatorClassNames` places the dividers at fixed 1/4, 1/2 and 3/4 offsets; change it together with the 2 and 4 column grid

## When not to use

- Seasonal departments to browse into, with no per tile price or buy button: use [Seasonal Categories](https://web.dev.reui.io/blocks/ecommerce/category-card/category-card-6.md) (`get_block("category-card-6")`)
- Catalog filtering and sorting above the tiles, with a live count: use [Rated Product Grid](https://web.dev.reui.io/blocks/ecommerce/product-card/product-card-8.md) (`get_block("product-card-8")`)

## Install

```bash
npx shadcn@latest add @reui/product-card-9
```

## About Product Card blocks

### When to use

- A catalog or collection page of items for sale, from a plain tile grid to one with filters and sort
- A similar items or latest arrivals row that pages through 4 tiles at a time with arrow buttons
- A single item quick buy panel with a size or finish picker beside add to bag and wishlist buttons

### When not to use

- Dashboard or admin tiles for metrics, records or settings, with nothing for sale: use the [Card blocks](https://web.dev.reui.io/blocks/application/card.md)
- Departments or collections to browse into, with no per item price or buy control: use the [Category Card blocks](https://web.dev.reui.io/blocks/ecommerce/category-card.md)
- A full page for one item with its gallery, spec tables, reviews and related items: use the [Product Detail blocks](https://web.dev.reui.io/blocks/ecommerce/product-detail.md)

### Agent notes

- `ProductCard` takes no props and renders demo items defined in its own files; add a prop to pass in your catalog
- Every `price` and `compareAtPrice` is a preformatted dollar string; format amounts and currency before you pass them
- Each page.tsx wraps `ProductCard` in a padded `min-h-svh` wrapper; strip it when the block sits inside your storefront layout
