Initially found this deal in an Instagram ad. VOLY is an on-demand 15 minute grocery delivery service which is currently operating in limited locations across Sydney's eastern suburbs, and north Sydney.
I can personally attest that this code worked for me, I just ordered 4 packs of muesli and the total charge came to $6aud. $14 of product, $2 delivery, $10 off. They even threw in a free avocado for me, and delivered in 13 minutes flat! Can confirm that it only works for the first order though, I tried to order again with the same promotion code and it threw an invalid promo code notification.
Does anyone have a screenshot of the available locations?
