Why Choose the Legacy Version

The Legacy version is designed for merchants who need to run a high number of volume discount offers at the same time and are comfortable using a draft-order–based checkout flow.

Choose the Legacy version if:

• You need more than 25 active discounts
  
  

• Your store runs many volume offers simultaneously
  
  

• You only require basic volume discount types
  
  

• You need metafield integration, FOMO messaging, or admin-level offer management
  
  

• You are okay with discounts being applied via Draft Orders rather than Shopify’s native checkout

If you need native checkout discounts, currency conversion, multiple cart offers, Bundles, or BXGY, the Function version is required instead.
