- **[Increase Cart Size Limits for a B2B Store](https://help.salesforce.com/s/articleView?id=commerce.comm_large_carts.htm&release=264.0.0&type=5)**  
    Most stores limit cart size to 500 line items per order. However, if your B2B store requires a higher limit, you can enable support to process up to 2,000 line items per order. To increase your line item limit, contact Customer Support.
- **[Improve Product Page Performance in a B2B Store](https://help.salesforce.com/s/articleView?id=commerce.comm_faster_add_to_cart.htm&release=264.0.0&type=5)**  
    To speed up the shopping experience in your LWR store, turn on the Faster Add-to-Cart feature. By splitting processing time across Product and Cart pages, Faster Add-to-Cart improves the response time on a Product page when a customer adds an item to their cart. This setting is enabled by default for B2B stores created in Winter ’24 or later and D2C stores created between Winter ’24 and Spring ’25.
- **[Enable Duplicate Cart Items for a B2B Store](https://help.salesforce.com/s/articleView?id=commerce.comm_enable_duplicate_cart_items_for_commerce_stores.htm&release=264.0.0&type=5)**  
    Let customers add duplicate cart items to their carts, instead of increasing the quantity of a single cart item.
