If we're running a sitewide sale, you'll be able to see details in the top banner of our website. (We won't be subtle about it — you'll definitely know!)
If we're not currently running a sale, the best way to find out about upcoming promotions or to receive coupon codes is to sign up for our newsletter. You can do this by entering your email address in the signup field at the bottom of the page.
We also now offer the option to pay using Affirm, which allows you to break up your order into 3 interest-free payments. You can read more about how this works here.
