Liven, a payment app for food venues is offering $10 off orders of $15 or more. Just redeemed on 2 phones so still works. One time use only per account.
Credit expires 21 days after redemption, and cannot be carried over from first use. Code is limited to 150 uses.
It works at the following locations:
QV - Lonsdale St
Monash Caulfield - Dandenong Rd
Collins Place - Collins St
Australia Square - George St
Central - George St
Chippendale - Central Park Ave
Burwood - Burwood Rd
I probably won't use a code but up to 66% off is a good ratio.
