Hi fashionista27, thanks for your post.
All coupons can vary from time to time, which is why we recommend checking the description of the email where you received the coupon in question. Alternatively, we recommend checking the T&C's of the coupon, and there you will be able to see what criteria you need to meet in order to use the coupon, including the time rage the coupon is valid for.
Thank you,
Marco
