Where Shopify native has the edge
Their advantage
Price
Free is hard to argue with for simple use cases.
Native reliability
No theme conflicts or extra scripts.
Attribution gaps on our side
Shopify Bundles aren’t tracked in Rebuy reports, and attribution breaks when merchants mix them.
Objections
“Checkout Blocks is free.”
Blocks is static. Show lift from personalized checkout offers against a holdout.
“We’ll use Shopify Bundles.”
Fine for fixed kits. Position Rebuy for personalized and subscription bundles, and confirm reporting needs.
