Sub-Love app provides online delivery and discount voucher management for Subway restaurants in the Luzern, Solothurn and Basel. Use our sandwich-builder feature, to fully customize your sandwich, wrap, or salad, and preview your protein, vegetables and add-ons on the fly, as you make your choices. Also, for any discounts received during shopping, your Profile in the app will hold your Vouchers, some of which you can use during online checkout, and some of which you will need to present on location, at the store, to the sandwich artist. Your vouchers are presented with a QR code, which are scanned by our team to check eligibility, so please have your app Profile page ready, if you would like to use voucher discounts in our locations in Luzern, Solothurn or Basel.
