A gift certificate of any amount to the Modern Device Store. These gift certificates cover anything in the shop, and are good for three years. Just order the amount you would like to give and the email address or addresses of the customer who will be using the gift certificate.
The gift certificate is a running total at the shop, and your can view your balance (and retrieve the code) at any time by logging into your account in the shop. You will have a chance to input the recipients name and email on the shopping cart page.
If you click the image at the top and click through to the second image, there is a larger image you can use to print for an envelope. It’s a little less generic than the email that gets mailed. Don’t forget to forward the email to the gifted party though, for reference and convenience.
