Thanks for this.
Ive already checked this out and just need help with the math,
I need to know how to work out the formula for every full £500 spent a discount of £25 is applied as long as they enter the cupon code.
So if they spent £500 and entered the cupon code, a £25 discount would apply,
£600 a £25 discount would apply, £1000, a £50 discount would apply..so its only on each full £500 thats spent.
