 "summary": "Shopify discount app (by Optizio) that folds several discounts into one code: order, collection and shipping discounts combined, a progress type that raises the discount as the cart grows, and checkout upsells on the top tier.",
 "best_for": "shopify stores running several promotions at once — an order discount, free shipping and a collection deal — that want shoppers to redeem them with one code instead of choosing, or that want the progress type which raises the discount as the cart fills",
 "skip_if": "you run one promotion at a time, because Shopify's own combined discounts already cover that at no cost — or the checkout upsells are the part you actually want, since those only exist in the $99.99 tier here",
 "honest_knock": "The two halves of the pitch are priced five times apart. Discount stacking — order, collection and shipping discounts redeemed with a single code — is the $19.99 Growth plan, the one the listing labels 'For Non-Plus'. The checkout upsells and linked discounts the app leads with sit in the $99.99 Unlimited tier only, so a merchant who came for the upsells is reading $1,199.88 a year rather than $239.88. There is no free plan to settle whether the stacking alone lifts an order, so the seven-day trial is the entire evaluation. One more thing to check before you commit: the Website link on the listing, www.stkbl.app, now redirects to the documentation for Discount Kit — a different, pricier Optizio app — and that documentation does not mention Stackable anywhere (checked 6 September 2026). For an app that launched on 13 October 2020 and has collected 54 App Store reviews since, ask support where the current documentation lives before the trial clock starts.",

Unlimited is $99.99 a month, or $999.99 a year on the same 17%, and adds unlimited checkout upsells and unlimited linked discounts on top of the same combined discounts. Both tiers come with a 7-day free trial. The plan table lists no order caps, credit allowances or per-use charges, so what the tier costs is what the app costs.",

  "name": "Smarty Discounts",
  "why": "Both extend Shopify's native discount engine, and the money separates them more than the feature lists do. Smarty Discounts has a free tier and tops out at $25.99 a month, and it aims at rules the native engine cannot express — capped and fixed-amount discounts that survive currency conversion, tiers by quantity and subtotal. Stackable aims at combination instead: several discounts under one code, a progress type that raises the discount as the cart grows, and checkout upsells in its top tier. So if the problem is 'this rule cannot be built', start with Smarty and pay nothing to find out. If the problem is 'my customers have to pick which code to use', that is Stackable's job — but there is no free tier here to test it on, only the seven-day trial."
