How to use add-on products on Everspring
Add-on products travel for free with a main product — a margin tool, not a standalone product. Learn what add-ons are, where to find them on the storefront, and the rule that ties them to a main product.

Add-on products are small items that travel for free in the box of a main product — extras like cards, plant food, or decorative hangers. They're a margin tool: you mix and match add-ons into an existing shipment without extra pick-and-pack or shipping costs. This article explains how they work, where to find them, and the one rule that keeps them from being standalone products.
💡 The short version: add-on products are not standalone products. Each add-on must travel with a main product from the same supplier — that's how it gets to the customer with no extra shipping cost. List add-ons as cross-sells alongside main products, never as standalone items.
What is an add-on product?
An add-on is a small item that fits inside the shipping box of a main product without changing the shipping rate. Typical add-ons in the Everspring catalog include plant care items (food, watering aids), small decorative accessories, cards, and similar lightweight extras.
Three things make them distinct from regular products:
They travel with a main product automatically. No separate logistics.
No extra shipping cost. The cost is already included in the main product's shipment.
Full margin. Because shipping is already covered, the add-on price is almost entirely margin minus your cost of goods.
Why add-ons are a margin tool
For a regular product, your shipping cost is covered once. Adding an add-on to that same shipment costs almost nothing extra to fulfil — but you still charge full retail to your customer. That makes add-ons one of the highest-margin items in your assortment when used as cross-sells or bundle additions.
Use them on your product detail pages ("Complete the look"), in cart upsells, or as part of curated gift bundles. See How to apply upsells and cross-sells for placement guidance.
Finding add-ons on the Everspring storefront
Each supplier on Everspring has a dedicated Add-on products tab on their supplier page. This is where you browse what's available alongside that supplier's main assortment.
Open the Suppliers section of the storefront.
Click into a supplier whose main products you already sell (or plan to sell).
Switch to the Add-on products tab.
Each add-on shows a Mix & Match badge and lists with its price. Add them to your import list, push them to your shop, and pair them with main products from the same supplier.
Add-ons cannot be sold as standalone products
An add-on only exists as an extra attached to a main product from the same supplier. Without a main product in the order, there's no shipment to ride along on — and the order cannot be fulfilled.
Practical implications:
Don't list add-ons as standalone purchasable items in your shop. Always tie them to a main product via cross-sells, bundles, or "complete the look" recommendations.
Pair within the same supplier. An add-on from supplier A can only travel with a main product from supplier A, not from a different supplier.
If a fulfilment is declined because the order contains only add-ons (or only add-ons from a supplier without a matching main product), open the order in Shopify, add a main product from the right supplier, and retry. If that's not possible, refund the order.
Next action
Open the Everspring storefront, go to a supplier whose products you already carry, and click the Add-on products tab. Pick three add-ons that fit your bestsellers, push them to your shop, and add them as cross-sells on those product detail pages. They cost almost nothing to fulfil and lift your average order value with little effort.
