## **Two classic bookstore promotions, now available as coupons in your store.**

Meet two new coupon types: **Buy N, pay M** and **Free shipping**. You can now run a 3-for-2 on a collection or cover shipping without changing prices or doing the math by hand.

## Buy N, pay M

- **Quantity promotions:** buyers take N titles and pay for M. The cheapest titles in each group go free.
- **You pick the titles:** choose which titles take part and set the combination, such as 3-for-2 or 2-for-1, with up to 6 free units per group.
- **Repeats per group:** if the cart completes two groups, the promotion applies twice.

## Free shipping

- **Shipping discount:** choose what percentage of the shipping cost the coupon covers, up to 100%.
- **Only where it makes sense:** applies when the cart has at least one physical product and the shipping method has a cost.

**Available in:** Dashboard → Coupons.

**Result:** more units per order, less friction at checkout and promotions your readers already know.
