I have a major problem.
I'm hungry and I am almost out of food at home. But I can't go to Coles because there is no Flybuys promotion to take advantage of.
Order takeaway!
Menulog
Affiliated Airline: Virgin (Velocity Points)
Earn: 2 Velocity frequent flyer points per dollar spent, making it the higher earner for takeaway home delivery
Net benefit per $100: 200 points
How to earn points: For each Menulog order, you will need to start by visiting the Virgin eStore and log-in to your Velocity account. Importantly, if you don't follow this first step, you won't earn Velocity points. Once on the eStore, search for Menulog or follow this
direct link 
and log in. Click the Start Shopping button and you'll be redirected to the Menulog site, then order as per normal.
Deliveroo
Affiliated Airline: Qantas (it's hardly surprising the flying kangaroo and Deliveroo are partners)
Earn: 1 Qantas frequent flyer point per dollar spent.
Net benefit per $100: 100 points
How to earn points: Download or open the Deliveroo App then go to My Account and add your Qantas frequent flyer number. Then order as per normal. Points can take a long time to reach your account (3 months).
