- Parents decide to give me a leaving home present of a new fridge (they didn't like my Gumtree/second-hand idea for this particular item)
- Go shopping with them. Choose an $850 fridge at Harvey Norman, on special from $1300. They give me the cash to buy it at the nearest Harvey Norman to my new place as it'll be cheaper for delivery
- Go to closer Harvey Norman, they have excess stock of the model I chose and it's $699 there
- Tell my parents about it, they tell me to put the extra towards something else
Profit all round.
