TryNow maintains partnerships with Stripe and a variety of card providers that enable us to keep a hold on a shopper’s card for up to 30 days. Visa, MasterCard, and American Express card holders will see a single hold on their card for the duration of their trial. Discover card holders are subject to a 5-day re-authorization process, which means their card will be re-authorized every 5 days to ensure that the funds are still available on their card to pay for their order. This is a part of our fraud prevention process. We only hold one authorization at a time, but it can take 24-48 hours for the expired authorization to drop from the shoppers statement.
