I have a layman's interested in pricing psychology and the various ways people can be "manipulated" into parting with more of their money by taking advantage of the way the brain works (it is more accurately described as causing more people to have a disposition to parting with their money than manipulation though because you cannot directly control individuals like you can groups).
Anyhow, I decided to try a little experiment: I tried shopping at Coles and ONLY buying items on the OZBargain Compare-a-tron pages, nothing else. Just for a laugh.
I was shocked. I was labouring under the delusion that I was a value orientated shopper who played the supermarket game well. I couldn't be more wrong. The last couple of weeks I have spent about 300% less on groceries. Yes, I'm that bad.
It's like the supermarket's have figured out how to completely skew my sense of value with every item I buy because when I'm not using Compare-a-tron I think I'm shopping well but being completely ripped off and when I do follow the Compare-a-tron method I can't see the value on the items I'm picking out but I spend 3 times less.
Thing is, I know rationally what they are doing because I have an interest in how people get manipulated - but I am completely unaware of it happening during the process. This is exactly how it should be according to what I've read, people do not know the manipulation is occurring so it's very hard to defend against but I guess I needed this little exercise to really ram it home what that mean's for me.
Conclusion: I am (hopelessly) not in control of getting value when I shop at a supermarket, they manage to make me believe I am getting great value whilst making me spend around three times as much as I need to.
Having a list and sticking to it is a good counter to impulse shopping. Thanks to the trons we can plan ahead.
