Loyalty Points cannot be used on 3rd party checkouts (i.e. Facebook, Instagram, Shop App). Exit from 3rd party checkouts and checkout from our ruti.com site directly to redeem points.
If you're in the shop app, scroll to the bottom and click CHECK OUT AS GUEST
This will take you out of the Shop App and into our ruti.com checkout where you'll be prompted to use your points! Just make sure you're logged into your ruti.com account.
