How do I use coupons

Could you set an expiration date that is far ahead? Basing off of the screenshot, it says the coupon long expired.

I get this issue too, and Kanalum's suggestions is the work around I use

Setting coupons expiration time to 0 doesn't work. Use the calendar and just set it for like a year or more.
