The June update (https://releasenotes.discountninja.io/release/X63yA-july-2022) includes better support for checking out "mixed" carts to allow for a discounted checkout with subscription and non-subscription products. The feature can be enabled in the menu Settings > Integrations > Subscription apps.

Does this address your integration needs?

Hi Harrison, the April update contains an improvement regarding how we work alongside Recharge. Cf. https://releasenotes.discountninja.io/release/UYTnb-april-2022

Specifically, the menu Settings > Integrations > Subscription apps now has the following option:

"Automatically detect subscription products in the browser and do not allow check out (does not require tagging of subscription products)".

This helps to allow Recharge to handle checkouts when Recharge is configured to use its custom checkouts.
