Just received an email from H&M about 15% sitewide.
According to the email, the 15% is only valid online.
Double points and extra 15% offers valid for new and existing members until 11.59pm AEDT 02.02.2021. Double points offer is valid in-store and online. Extra 15% off offer is valid online only.
Nice discount. Unfortunately, the stock left is either awful, or limited in sizes.
