The addition of the "coupon code" is great, but just a few details that might have been overlooked so far.
- When you enter the code, it takes you back to the subscription list. Then click on the subscription again and enter the code again and THEN it accepts it.
- When you enter a non-existent code, it accepts it, though it doesn't change the price. Some feedback that the code doesn't exist would be handy.
- The formatting, colour and font-sizing is rough around the edges and could use basic polish.
