When you register a new debit or credit card to your Plant Cafe account, we conduct an authorization hold. This is a temporary charge on your account for $1 as a test to ensure the card will work well with our app. That way, when it comes time for you to make your first purchase, there will be no issues processing payment.
This $1 authorization hold will always be removed from your card. Typically, you should see it refunded after 1-5 business days, but it may take as long as 30 days depending on the bank. It never actually gets charged!
