Stop charging double shipping
on bundled orders.

When a customer adds a sticker, coozie, or sample to a real order, Shopify charges them shipping twice. TagAlong waives the addon shipping automatically at checkout.

How it works

1. Mark addon products. Tag any product with shipping_addon, or set the tagalong.is_addon metafield to true.
2. Create an automatic Shipping discount.In Shopify admin, create a new discount and select “Bundle shipping discount” from the TagAlong app. Save — no other configuration needed.
3. Done.Any time a customer orders an addon alongside a non-addon main item, the addon's shipping line shows “Free with bundle” at checkout.

Why use TagAlong?

• Recover lost conversions. Customers abandon checkouts when a $4 sticker triggers an extra $9 shipping fee. TagAlong removes that friction.
• Zero merchant config. Two ways to flag a product (tag or metafield). No rule editor, no thresholds, no edge cases to babysit.
• Built on Shopify Functions. Runs at the checkout edge in milliseconds. No script tags, no theme modifications, no API rate limits.
