Most likely, if your transaction was declined initially (i.e., the billing zip code being entered incorrectly, the webpage did not refresh properly, etc.) then subsequently approved, the card issuer may indicate on your statement that funds are "pending". Only approved transactions are processed and pending transactions are not an indicator that we have charged you additionally. These pending transactions fall off of your account in 1-3 business days at your card issuers discretion, as we only process approved transactions. If more than one transaction for the same order settles, please feel free to contact us so we can resolve any issues.
