Don't feel bad, you are doing your bit for the economy! If people who could afford it, didn't buy the more expensive things, or didn't spend as often, then more people would lose their jobs and the economy would be worse off than it is!

People need to buy so we can employ people in retail and manufacturing and transport.

Also, if you buy Australian, you are helping locals who struggle to compete against cheap asian imports.

So spend away my friend!
