Give shoppers a reason to buy more than one.

Sledge is a Shopify bundle app that runs nine offer types on one bill, including fixed bundles, Buy X Get Y, volume discounts and build-your-own bundles. It is built to make buying more the better deal. Sledge creates each discount in Shopify, so shoppers get that deal without a discount code.

Shopify’s own Bundles app sets a bundle’s stock from its scarcest item, divided by how many of that item the bundle needs. Shopify tracks that stock as one total, not per location. A Sledge fixed bundle checks each item on its own and stays open while every item has stock. If an item hits zero, Shopify’s cart and checkout limits still apply. Here is why a bundle shows sold out and how to fix it.

Yes, in Sledge, on every plan. Tiers such as buy three save 10% and buy six save 21% sit inside one volume discount. A Buy X Get Y offer can have one tier or several, such as buy one get one free and buy three get two free. Each offer runs as one Shopify discount, which Sledge updates when you edit the offer and removes when you switch it off. A volume discount and a free gift can both apply in one cart. Shopify allows up to 25 active automatic discounts, app discounts included. Sledge offers combine with other discounts where Shopify’s rules allow.

With Sledge, yes. Every offer type except build-your-own takes a start and end date, and its Shopify discount opens and closes with those dates. Any offer can wait as a draft until you switch it on. Your list of offers shows each one’s visitors, clicks and revenue over the last 30 days, so you can see what it earned.

On any paid plan, Growth Intelligence reads your real orders and lists a fix for products that sell together. Click “Create Bundle” on that fix and the bundle opens filled in, so you review it and save it to go live. Growth Intelligence then checks the result against real sales. The fixes add up to one estimated total in your store’s currency, labeled “Est. potential”.

With Sledge, yes. An A/B test shows each shopper one version of the offer for their whole visit, then compares how the versions sell, so you can keep the one that sells more. The free trial allows three A/B tests, and every paid plan allows unlimited tests across your offers.

In Sledge, yes. A fixed bundle, a Buy X Get Y or a volume discount can launch as a pre-order, so shoppers can order the whole set before it ships. Where your payment gateway and country support it, you can take a deposit instead of the full price. Here is how pre-orders work in Sledge.

In Sledge, a fixed bundle sells a group at one price, set as a percentage or a fixed amount off. Volume discounts and add-ons show on the product page. A build-your-own bundle gets its own page, set out in steps, and you can set a discount for each step. Buy X Get Y applies its reward in the cart, a free gift joins the cart at your goal, and shipping can show a free-shipping bar. Subscriptions run on their own selling plans, and the thank-you page offer checks out as its own order. Our guide shows how to create and price a bundle.

No, all nine offer types come with every paid Sledge plan. Sledge starts with a 14-day free trial, and you can run one active offer of each type during it. Pick a paid plan during the trial and billing starts when the trial ends. Sledge is free on development stores. Compare the plans on the pricing page.
