Basic
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureWhen another app creates a discount code, it defaults to not combining with your other discounts, and no store-wide setting changes that. Customers lose promotions you meant them to have. CombineSync groups your discounts by the app that created them, from Shopify's own record. You choose what each app's discounts combine with: product, order and shipping. Nothing changes until you ask.
Some third-party platforms like Klaviyo, Facebook, Instagram and Loox automatically create discounts in Shopify - but they don’t enable the "Combinations" setting. As a result, those discounts can’t be used together with others, such as shipping discounts or order-level discounts, unless you manually fix each one. Unlock Combine Discount automates this for you.

FAQ
CombineSync and CS: common questions
- Is CombineSync or CS cheaper?
- Only CombineSync lists a free plan. Paid plans start at $4.99/month for CombineSync and $2.99/month for CS. Shoplist compares base prices only between monthly plans in the same currency; usage charges and annual plans vary, so check each plan’s limits.

- CombineSync lists 2 the others don’t mention, such as Bulk editing, Filtering. CS lists 3 the others don’t mention, such as APIs and webhooks, Coupons, Triggers and rules. A feature missing from a listing may still be supported; this compares what each App Store listing says.
- Where does this comparison’s data come from?

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 14, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
