If you ever travel into the past in a modified DeLorean and just so happen to stop your mum from running over your dad, you’ll need a pair of Calvin Klein undies to keep her from discovering your identity. The good news is that Dugg has 25 per cent off CK undies at the moment.

To get the discount, enter the code ck25 at the checkout. Given a single pair of CK undies can cost up to $60, saving 25 per cent suddenly appears to be a lot more appealing a proposition. There’s free shipping too, which will help you save up for that time travelling DeLorean you always wanted!
