If you have signed up to the email mailing list you can use the code made available to you for 15% off one order at any point in time.
Note also that if you sign up to the Pretty In Punk loyalty scheme, "Punk Points", you can collect points that equate to money off purchases. You can find the sign up in the bottom right hand corner of the screen. At present 500 points will save you 5€ on any purchase over 10€ and 375 points will get you free economy shipping.
Codes are valid once per customer, can not be applied retroactively, and can not be combined with any other offer. Orders placed separately can not be combined at a later date. Coupons are redeemable only on prettyinpunk.co, and NOT the TeePublic store. For more information on TeePublic please read these FAQ.
