Sometimes credit/debit card statements contain two transactions, but this is only temporary. When a purchase is made, an authorization charge is placed on credit/debit cards which temporarily hold funds. This is not actually a charge on your card. Once the order has been shipped, this authorization becomes an approval and charges your account. The authorization falls off under 72 hours from when you ordered.
For your security, we may pre-authorize $1 to verify your billing address and credit/debit card information. If successful, we’ll charge the full amount of your purchase (plus sales tax and shipping) once your order ships. If this $1 pre-authorization fails, we will not authorize your purchase. The $1 pre-authorization will drop off from your account within 2-3 business days.
