Most of us see coupons and put them straight in the bin.
We use our fuel cards mainly to scrape off the frost on our windscreens in the morning.
But some take their discounts to the next level, and here's how Kiwis are cashing in.
Only chumps pay full price - website PriceSpy instantly gets you the cheapest store within a few clicks.
Got the munchies on a budget?
Just Google search food coupons. Do it for pizza and you'll find hundreds of forms, where the latest discounts are continuously updated.
What about discounts that aren't on the internet?
If you're only saving a few cents with that fuel discount card, you're missing out.
Anne Thompson from Christchurch jumped on BP's AA Smartfuel savings challenge, and did so well, she was crowned the "discount queen".
Only filling up $40 at a time, she gets multiple discounts on just one tank.
Combine that with swiping it at partnered stores such as Countdown, she's getting $2 off per litre.
"Filling your tank for nothing - it's the best feeling ever," Thompson told The Project.
How about free concerts?
Put a radio station's phone number on speed dial, listen out for competitions, and turn winning prizes into an art form.
For 20 years, Dim Pivac has won hundreds of free tickets.
"[It would] be a weekly basis - winning tickets, winning records - all sorts of stuff," he said.
"I've won hundreds and hundreds of prizes."
