Everything else in the order earns at the standard rate. **Where to find this:** Shopify admin → Apps → Yuko Loyalty → Loyalty → Programs → Booster Campaigns → Create campaign → **Product & Collection Multiplier** ## Overview A Product & Collection Multiplier boosts points only for the part of an order that matches the products or collections you pick. If a customer buys a boosted item and a regular item in one order, only the boosted item's share of the order earns the multiplied points. It always works on the **Place an order** Way to Earn. ## Why you need it? A store-wide multiplier rewards whatever the customer happens to buy. When you want to steer attention to a launch, a hero category or overstock, you need the boost to apply to those products only, so you don't pay extra points on everything else. ## When to use it? * You're launching a new collection and want to drive traffic to it. * You want to move slow-selling or overstocked items without marking them down. * You want a permanent earning advantage on a high-margin category. * You want to promote a seasonal range (gifting, summer, back-to-school) for a few weeks. ## Before you start The **Place an order** Way to Earn is enabled. If it's off, this type is greyed out in the **Create Booster Campaign** picker. ## How to configure it? Go to **Apps → Yuko Loyalty → Loyalty → Programs**. In the **Booster Campaigns** section, click **Create campaign** and select **Product & Collection Multiplier**. Enter a **Campaign Name** (internal) and an optional **Description**. In **Products & Collections**, click **Browse** next to **Products** and/or **Collections** and pick the items. You must select at least one product or collection. Click **Add Reward**. Enter a **Name** (visible on the storefront) and the **Multiplier**, a value between 1.1 and 10.0. The campaign has exactly one reward. Add **Targeting Rules** such as **VIP Tiers**, **Customer Tags** or **Membership**. Set **Max participants** and **Max completions per customer** if needed. **One-time**, **Recurring** or **Evergreen (always on)**. Keep **Stackable with other campaigns** checked, or uncheck it to make the campaign exclusive. Check **Ignore if customer earned VIP tier multiplier** to skip the boost on orders where the customer's VIP tier already gave them a bonus. The **Body text** widget label defaults to *"Earn extra points on selected products & collections while this campaign is live."* Available tokens: `[title]`, `[reward]`, `[points_label]`. Keep **Online store** selected under **Publishing** and choose an **Icon**. **Status** is enabled by default. Click **Save**. ## How it works 1. A customer places an order and earns their normal **Place an order** points. 2. Yuko works out how much of the order subtotal comes from the selected products or collections. 3. The bonus is **base points × (eligible subtotal ÷ order subtotal) × (multiplier − 1)**, credited as a separate entry. 4. If nothing in the order matches, no bonus is added. **Example:** a 2× campaign on your *New Arrivals* collection. A customer places a $100 order (earning 100 base points) where $60 is from *New Arrivals*. They get 100 × 0.6 × 1 = **60 bonus points**, for 160 in total. ## Use cases / Examples **1. Collection launch week.** 2× on the new collection for its first week (**One-time** schedule). **2. Overstock clearance.** 3× on a specific overstocked product for 10 days, instead of a markdown. **3. Evergreen hero category.** 1.5× on your highest-margin collection, always on, so customers learn which range earns fastest. **4. VIP-only launch.** 2× on a new collection with a **VIP Tiers** rule for your top tier, as an early-access perk. ## FAQs Yes. If both campaigns are stackable, a matching order gets both bonuses. Each bonus is calculated on the base order points, so they add up rather than multiply each other. No. This type only works on orders, because it needs the order's items to check against your selection. This type has its own **Products & Collections** picker, so those targeting rules aren't offered. ## Next Steps Schedule, targeting, stacking and display settings shared by all boosters. Multiply points on every order, or on any other earning action. Show the campaign on every storefront page. The base Way to Earn this booster builds on.
