Yesterday, I issued a 25% off coupon for Saturday - but I accidentally made it valid on Sunday, instead!  Oops! 
I'm sorry if you were affected by my mistake.

I have taken the following steps to fix it:
1. Changed the coupon!
2. Changed my request 'buffer zone' so that it's now possible to book a lesson from 12 hours in the future; so you can still take advantage of the coupon for tomorrow.  (I will be changing this back tomorrow.)

Sorry again!
