But there is one trick you can try which will guarantee you a spot at a shopping centre.
According to mathematician Joe Pegano, if you wait – or circle around – for up to 6 minutes, a spot will become available.
This is based on the statistic that the average person spends 120 minutes shopping.
You just need to find an aisle with at least 20 cars parked on it – ideally 10 on each side.
“I developed this because I’m trying to show how mathematics can actually work in the real world,” Mr Pegano told Inside Edition.
