Select Items: Browse the tknogy.com store online and choose the items that you wish to purchase. Checkout: After you have added all desired items to your cart, proceed to the checkout page. E-Gift Card Code: On the payment page, there should be an option to enter your e-gift card code or number. This is typically a unique alphanumeric code provided to you when the e-gift card was purchased. Apply the Code: Enter the code in the designated field and apply. The value of the e-gift card will be deducted from the total amount of your purchase. Remaining Balance: If the value of your purchase exceeds the amount on the e-gift card, you will be required to pay the difference using another payment method (like a credit card). If the purchase amount is less than the e-gift card value, the remaining balance will typically stay on the card for future use. Confirmation: Once the payment is processed and accepted, you'll receive a confirmation message or email indicating your order has been successfully placed.
