This came up with workmates during some casual banter. They know I am a huge OzB fan and always recommending them stuff. I did a quick stocktake of my discretionary spend as part of some budgeting for 2020 and surprisingly almost all my discretionary (and most essential) purchases were OzB influenced. I'm on the app twice a day at least and have gotten better at not buying stuff I don't need even if it's cheap (looks at eneloop pile) but also tend to consult OzB more and more.
I calculated I spent about 80% of my discretionary income (ex food, coffee, bills, mortgage etc.) on OzB influenced buys and this tallied up to about $15k for the year. If not for my hobby of cycling and the purchases there, it would have very well been 100%. Even if I find something that isn't on OzB I tend to cross search "item" + 'OzB' via google just to make sure lol.
What does your OzB financials look like?
