How does the promotion work?
If you make a purchase over $30, you can get $10 off by simply signing up to join our BWS Online Community.How do I claim the discount?
This offer will only be available if there are participating employees in store at the time that you visit (i.e. BWS employees with the promotional QR code.) When in store with a participating team member, you can scan their individual QR Code with your phone. You will then be taken to a landing page where you will be asked to provide some details, including your email address. Once you have filled in your details, you can click the ‘Redeem Now’ button - this will start a 5-minute timer.
Please show this screen to a staff member and they will help you redeem your $10 off offer.

I've provided a working link for the QR code as an example only as the terms of the promotion require you to be in store to scan a QR code, the promotion does have an incentive for team members to get sign ups so if you have a team member who has treated you well then sign up using their code for a win-win.
Sounds a little painful
