Our Take

Amplify is useful when a Shopify offer needs more flexibility than a simple product discount: a build-your-own bundle, a quantity break or a coordinated cart incentive.

Several bundle and upsell formats
Inventory-aware offer logic

Grow costs vary with generated revenue
Scale requires a yearly commitment

Best for:

Small teamsGrowing businesses

Best use case: Launching a mix-and-match product bundle with synchronized inventory and clear discount rules.

Most relevant to stores actively managing bundle offers and enough revenue to justify usage charges.

Read the full assessment

Amplify is useful when a Shopify offer needs more flexibility than a simple product discount: a build-your-own bundle, a quantity break or a coordinated cart incentive. The range of offer formats is valuable only if the rules remain understandable to the shopper. Start with one bundle and validate inventory, discount stacking and mobile checkout. Compare Grow’s usage-linked bill with a Scale quote once the program has consistent volume.

About Amplify

PickyStory now operates under the Amplify brand. The Shopify platform creates fixed and customizable bundles, quantity offers and upsells across product, cart and post-purchase surfaces. Inventory and discount logic connect the offer to the store’s underlying products, with an API available for custom presentation. The main choice is between usage-linked Grow pricing and a negotiated fixed Scale package. Free development-store access is for building and testing, not an ongoing free production subscription. Plan the bundle rules, discount combinations and checkout behavior before launching offers.

Cost considerationsBilling, usage limits and additional fees

Grow starts at $99.50/month and uses additional pricing tied to revenue generated with Amplify. The published page positions it for stores up to $30,000 monthly revenue but does not provide a complete usage-rate table; enter the full estimate from the account. Scale has a negotiated fixed monthly fee with a one-year commitment. A 30-day trial is advertised. Shopify development stores are free for testing. Shopify itself, payment processing and the cost of discounts remain separate.
