Coupons now work through their last day
- What was broken
- A coupon expiring today was rejected from midnight, because the expiry date was read as the very start of that day. One applied the day before stopped working at checkout.
- What I changed
- A coupon now stays valid until the end of its expiry date and is rejected from the next day.
- Why it matters
- Customers get the discount for the whole last day the shop promised.
