Purchasing items through TryNow or a subscription are separate payment options. Shoppers are able to choose between TryNow (where the shopper can try before they buy) or they can choose to purchase and subscribe.
Shoppers are not able to check out with a mixed cart of TryNow and subscription items. We recommend disabling the alternative option once an initial purchase option is selected for an optimal shopper experience, but strategies are dependent on your existing subscription setup.
If you have subscriptions on your site, you'll need to work with your Growth Strategist to develop a strategy for ensuring a seamless customer experience.
