For those wondering if there's a catch: yes, sort of. If you want the full 50% off, you'll need to sign up for the brand's loyalty program, which is free on its website but does require you to submit your full name and email for point-based rewards and birthday gifts. If you're looking for a one-and-done shopping experience, non-members will still get 40% off. Either way, both program members and non-members have to enter the code 'FLASH' at checkout to save.
