Same Products, Same Traffic: How Product Kits Pushed AOV from $66 to $85 on Shopify

By Steve Merrill | May 15, 2026

$66.84 to $85.33. That's a 27.6% jump in average order value. Same product catalog. Same Meta ads. Same audience targeting. The only thing that changed was how the products were packaged and presented.

This was a jewelry brand, handmade pieces with a small but loyal customer base. They were doing solid volume but watching their cost per acquisition creep up quarter over quarter. More ad spend, slightly worse returns. The usual story. We didn't touch the ads. We built kits.

What Is a Product Kit and Why Does It Change the Math?

A product kit is a bundled offer that groups two or more individual products into a single purchasable unit, usually at a small discount from buying them separately. The mechanism is simple: give a customer who was going to buy one thing a compelling reason to buy two or three things in the same transaction.

The math shifts immediately. If your current AOV is $66 and your CPA from Meta is $22, your ROAS is 3.0x. Push AOV to $85 with the same CPA and your ROAS is 3.86x. You didn't improve your ads. You improved what customers buy when the ad works.

This is the part that surprises most store owners: you don't need better traffic to grow revenue. You need the traffic you already have to buy more per visit. Shopify's own research consistently shows AOV improvements deliver higher margin gains than equivalent traffic increases, because you're not paying extra acquisition cost for the incremental revenue.

How Did We Build the Kits for This Brand?

Start with the data. We pulled first-purchase reports from Shopify Analytics to find the anchor SKU, the product most customers bought first. For this brand, it was a specific pair of stud earrings at $28. Appeared in roughly 41% of all first orders.

Then we pulled frequently-bought-together data. What else showed up in multi-item orders alongside those studs? Two products appeared consistently: a small pendant necklace ($24) and a ring-and-earring care kit ($18). That's your kit.

Kit pricing went in at $62 for all three pieces. Individual retail total was $70. Customer saves $8. Not huge, but meaningful at this price point. More importantly, the kit now had a story: a "starter set" that gave someone new to the brand a complete look, not just a single piece.

We built it using Bundler (the Shopify bundle app) as its own SKU. Single product page, single checkout, single tracking. No custom development required.

What Happened to Conversion Rate When Kits Launched?

Dropped slightly. This is normal and expected. The kit costs more than a single item. Some customers who would have bought one piece at $28 looked at the $62 kit and bought nothing that session, or came back later for the individual item.

Total transaction count was roughly flat month over month. But AOV went from $66.84 to $85.33 across the store. Revenue went up 12.7% in the first full month of kit availability without changing ad spend at all.

I've seen a version of this play out at probably a dozen clients now. The conversion rate concern is almost always the first objection from store owners, and it's almost always the wrong thing to improve for. Revenue per visitor is the number that matters. A 5% dip in conversion rate paired with a 27% AOV increase is a very good trade.

How Should You Price Kits to Protect Margin?

The pricing window that tends to work: 85-90% of the sum of individual retail prices. This produces enough perceived savings to motivate the decision without training customers to hold out for bundled pricing on everything.

Where brands go wrong is going too deep. A kit priced at 70% of component value looks like a clearance move. It attracts deal-seekers who don't return. And if the kit becomes the dominant way customers buy, your effective per-unit revenue drops below where it was before you launched it. You've traded AOV improvement for margin compression.

The $62 kit on a $70 component total is an 88.5% ratio. That's the zone you want to be in.

Which Products Work Best as Kits?

The answer is: products with natural use-case companions. Pieces that go together in real life, not just in a spreadsheet.

Jewelry with care products. Skincare with applicators or minis. Food products with prep tools or recipe cards. Craft supplies with beginner materials. The customer should look at the kit and think "obviously" rather than "why are these together?"

Forced combinations don't work. A candle bundled with a completely unrelated home decor piece because both happen to be SKUs that aren't moving, customers see through it. The kit needs a coherent story in one sentence or less.

For this jewelry brand, "a complete starter look" was that sentence. Easy to say. Easy to understand. Easy to buy.

Does the Kit Offer Work in Ads or Just On-Site?

Both, but they work differently.

On-site, the kit competes with individual products on collection pages and in recommendations. The visual presentation (showing all three pieces styled together) does a lot of the selling. Customers browsing collections who might have bought one thing see the kit image and start doing math.

In ads, the kit needs a different creative approach. Individual product ads show one piece. Kit ads show the full set styled as a scene, "everything you need to complete the look." That framing works well for cold audiences who haven't seen the brand before and need to see the full picture quickly.

We ran kit creative against individual product creative in a straight A/B test over 4 weeks. Kit ads lost on click-through rate (the single product image was cleaner and more thumb-stopping) but won on ROAS by a meaningful margin. Lower click rate, higher revenue per click. That's fine. Improve for what pays the bill.

FAQ: Shopify Product Kits and AOV

What is a product kit on Shopify?

A product kit on Shopify is a bundled offer that groups two or more individual products into a single purchasable unit, usually at a slight discount from buying them separately. Kits increase average order value by giving customers a reason to buy more in a single transaction.

How much should I discount a Shopify product kit?

Price the kit at 85-90% of the sum of individual item retail prices. This creates meaningful perceived savings without destroying your margin. Deeper discounts tend to attract deal-seekers and can train buyers to wait for bundled pricing.

Which Shopify apps are best for product kits and bundles?

Bundler and Fast Bundle are the two most widely used Shopify bundle apps. Both support fixed bundles, mix-and-match bundles, and tiered pricing. All major bundle apps integrate with Klaviyo for email marketing of kit offers.

Does bundling hurt conversion rate?

Sometimes, slightly. A higher price point can reduce the total number of buyers. But a small drop in conversion rate is usually more than offset by the AOV increase, meaning total revenue goes up even if transaction count goes down. Measure ROAS and revenue, not just conversion rate.

What types of Shopify products work best as kits?

Products with natural use-case companions work best: jewelry with care products, skincare with applicators, food products with prep tools, craft supplies with starter materials. Kits fail when the bundled products have no logical relationship in use.
