Pumper works much like SMART: an offer block on the product page, tiered discounts on the products themselves, and no bundle products to manage. The differences are the revenue cap, the integrations each app names, and what each does beyond the product page.

Sources, checked 2026-11-02: Pumper Bundles Quantity Breaks on the Shopify App Store, which is where the Pricing menu on pumper.run leads, and Pumper's bundles page, which repeats the same plan prices. Prices are USD list prices and features are taken from Pumper's own wording on the date checked. Pumper's homepage FAQ mentions a $39.99/month maximum; we used the $49.99/mo Unlimited plan shown on the listing. Pumper is a trademark of its owner; E-TRADE PARTNER is not affiliated with it.

When Pumper fits better
- You take cash on delivery through Releasit COD or EasyCOD. Pumper's listing names both. SMART has no integration with COD form apps.
- Your cart drawer is Monster Cart, AMP Slider cart, Opus Cart or qikify. Pumper's listing names those drawers. SMART names only UpCart among cart drawer apps and relies on standard theme cart events for the rest.
- You want chat support around the clock on a free plan. Pumper lists chat support Monday to Sunday, 24/7 on every plan, Free included.
When SMART Bundles fits
- Your offers bring in more than $300 a month and you'd rather not pay for that. Pumper's paid plans start at $9.99/mo once extra revenue passes $300; SMART stays free at any volume.
- You want more on the product page than Pumper's listing and site describe: an Alternative product card, a countdown timer, and progressive gifts whose steps can include free shipping.
- You need discount logic Pumper's listing doesn't describe: an Advanced discount that combines product, order and shipping discounts under conditions such as country, postal code or customer tag, automatic or with a code (advanced discounts).
- Your team works in Shopify admin in Polish, Czech, Danish, Hindi or Russian, for example. Those aren't on Pumper's listing; SMART's admin is available in 25 languages and switches with your Shopify admin.
Where each offer can appear
Pumper places its offer above the Add to cart button and supports page builders such as GemPages and PageFly. SMART does the same by default: the widget inserts itself above Add to cart once the SMART Discounts app embed is on. You can move it with the "Bundle widget" app block, paste an HTML snippet into a page builder, or show a chosen product's bundle on the homepage with the "Bundle widget for a chosen product" block (place the bundle widget). In SMART, the offer stays on the page: after an add, the cart drawer refreshes, but there is no widget inside the drawer or at checkout.
