Try it: pick a tier. These are the numbers the shopper sees at checkout.
Buy 2 save 10%, save a fixed amount on each item, or set a price like 3 for 999, with an optional label like Most popular. Tiers count across sizes and colours, and picking one sets the quantity in your theme's own buy box. Run them on chosen products or a whole collection.
Sell two to five products together at a percentage off, a fixed amount off or a set bundle price. Shoppers can pick the size or colour of each item, one button adds the whole bundle, and the discount applies only when every item is in the cart.
Suggest up to four add-ons under a product. Shoppers tick what they want, choose options, and see exactly how much they save. The add-on discount applies only alongside the main product.
Any 2 for one price, any 3 for less: shoppers combine any products from a collection or your own list, in any variants. The offer shows on every product it covers, with a link to shop the rest.
Buy 1 get 1 free, buy 2 get 1 half off, or buy a snowboard and get the wax free. The reward can be the same product or a different one, and can repeat for every set in the cart.
Free shipping, a free gift and spend more, save more tiers (spend 1,500 get 5% off, 2,500 get 10% off) show as progress at the top of the cart page and cart drawer, with one-tap products picked to close the gap. Shoppers add the free gift with one click, and it comes back out if the cart drops below the goal.
Set the accent colour, button text colour, background and corner style from your theme editor, and change every word shoppers see, in any language. Kartwise uses your theme's fonts.
A live preview sits next to every offer while you edit, using your real products, prices and theme colours. For cart goals, slide an example cart total to see each message shoppers will get.
Analytics shows how many shoppers saw each offer, how many added to cart through it, and the value added, by day and by offer. Plus the orders that used a Kartwise discount, as counted by Shopify.
Your dashboard lists every offer and shows whether the product page block, cart bar and checkout discount are switched on. A short checklist walks you through setup and hides when you're done.
Kartwise runs as automatic Shopify discounts. The prices shown on your product page match the cart and checkout to the cent, with no codes to type.
Approve the 3-day trial on Shopify's plan page. Billing goes on your regular Shopify invoice.
Choose an offer type, pick products with Shopify's product picker, set your discount and watch the live preview. Save, and it's live.
One click opens your theme editor with the Kartwise block on your product page; another turns on the cart bar. Save the theme and you're done.
Check Analytics to see which offers shoppers use most, then adjust tiers or pause what isn't pulling its weight.

It works with any theme that supports app blocks (Online Store 2.0), including Dawn and Horizon. It uses your theme's fonts, and you set the colours, corners and wording in your theme editor.
Yes. Every word shoppers see, from "Buy more, save more" to the cart bar messages, can be changed in the theme editor, in any language.
It works on the cart page and in Dawn- and Horizon-style cart drawers, and updates as shoppers change their cart. You choose where it shows.
Yes. Kartwise combines with order and shipping discounts. If an item already has another product discount, Shopify gives the shopper the better of the two. Spend tiers don't stack with your own order discount codes.
No. Each item gets one offer. Free gifts, bundles, frequently bought together and buy X get Y come first; where mix and match and quantity breaks overlap, the shopper gets whichever saves more.
The dashboard shows whether your product page block, cart bar and checkout discount are on. Analytics shows views, adds to cart and value added for each offer.
There are no subscription, wholesale or digital bundles, no warranties, gift wrap or shipping protection add-ons, no A/B testing, no custom CSS editor and no POS support. Analytics counts adds to cart through Kartwise, not order revenue.
No. The discount is applied automatically in the cart and at checkout.
No. It stores your offer settings and anonymous daily counts of offer views and adds for your Analytics page. It never reads or stores customer names, emails, addresses or orders.
The block and cart bar disappear from your store and the Kartwise discount stops applying. Your offer settings and counts are deleted when Shopify sends its data-deletion request.
