Visit the Dexter store website or physical location where the card is accepted. If shopping online, add your chosen items to the cart. At checkout, enter the unique Dexter Gift Card code manually in the payment section. If in-store, present the digital or physical gift card code to the cashier; it will be manually keyed into the POS system. The gift card amount will be applied to your purchase total. Complete the payment for any remaining balance if needed. Keep the gift card code secure as it cannot be re-used once redeemed.
