There are more varieties of designs offered online as compared to a physical purchase from the mall. The delivery of Simon gift cards usually takes a few days, but an express overnight delivery is available at an extra charge.

Simon gift card balance can be checked online. The available denomination ranges from $20 to $500 exclusive of shipping and handling charges.

How does it work?
The first step is your personalization. You pick from our card designs and personalize it with the gift recipient’s name and your message.
The Simon Giftcard looks and acts like a credit card. Unlike a credit card, the Simon Giftcard stores value: the dollar amount you prepay.*
As the gift recipient uses the card, the amount of the purchase is automatically deducted from the card’s available balance. When the available balance is reduced to zero, the gift recipient can keep the card as a memento of your gift. If the card is lost or stolen with a balance remaining, the gift recipient can cancel the card and order a replacement. See terms and conditions for further details.

How much does it cost?
The total cost is the amount you choose to give – from $20 to $500 – plus shipping and handling charges. Shipping and handling is $5.95 for the standard Simon giftcard and $6.95 for the custom cards, such as the Longhorn, Indiana University and Purdue Giftcards. Express shipping is available for all Simon Giftcards for an additional charge.
