I saw a discount code promotion on your store. Am I able to use the discount on a future date?

Typically no. These are special one-off promotions that require the code to be used before it expires. Since they are rare, I would recommend that you use the code and place an order immediately. You can arrange for later pickup or possible amendment to your order by emailing support@jenshansen.com, and we will help (for example if ring size and engraving details are not known immediately you can always advise these later).
