It’s terribly simple.
Make your way to the sign-up page of any workshop you’re eager to take part in and scroll to the Sign Up section. If you’ve any discount available in your account you’ll spot the Apply a Discount link sat neatly under the price.
A dialogue will then popup up. In this dialogue you’ll see a neat little slider that you can use to set how much of your discount you’d like to use. Once you’ve set a percentage and you’re happy, hit the Apply Discount button.
The dialogue will then disappear and you’ll notice that the price has been modified accordingly. Take a moment to relish in the savings you (assumedly) rightly earned and, when you’re ready, hit that Sign-Up button.
And that’s it; there’s nothing more to it. Further still, discounts are stackable so, for example, if you’re taking full advantage of the Refer-a-Friend scheme and five of your family, friends and coerced stranger encounters sign-up for a workshop, you’ll find yourself with enough discount to sign up to any workshop entirely free of charge.
