## TL;DR

One link can send a customer straight to checkout with products in the cart, a discount applied and their email filled in. Here is how Shopify cart permalinks work and how to use them safely.

## Key points

- The customer has already decided, for example a reorder reminder.
- The offer is a specific bundle, for example "the starter kit".
- The buyer is on mobile and typing is painful.
- A sales rep has agreed the order with the customer and just needs them to pay.
- Email and SMS campaigns. "Reorder your usual" with the customer's last products and email prefilled.
- Influencer links. A link that loads the featured product with the influencer's code already applied, so followers do not have to type it.
