Most volume discount apps hide the offer until checkout, so shoppers never get a reason to add one more. Most bundle apps keep their own stock count, which drifts until you oversell. Bundlo shows every tier as a selectable card on the product page, and expands bundles into their components in checkout so Shopify deducts real stock. Rules run as native Shopify Functions and take one of your 25 discount slots, however many you build. Analytics, mix and match and A/B testing are in every plan.

• Selectable tiers on your product page, so shoppers see the saving up front
• Bundles deduct component stock in checkout, so you never oversell
• One discount slot total, however many rules you build
• Mix and match, scheduling and A/B testing are in every plan
• Exact per-rule attribution you can export and check yourself
