Yes, I'm officially a tightwad.
My eldest son (6) was excited that I've noticed and picked up a 5c coin twice this week (the money goes into his money box). I'm a bit worried though, that he wasn't impressed that it was "only" a 5c coin, and that it would take 20 of them to make $1. Stopping to pick up small change must run in our family though, because he told me that his Grandpa and done the same thing the other day.
And then, yesterday, I spent an hour in the city walking around two of the large uni campuses sticking up notices on the student notice boards - I'd printed out some info on how to open an account with EasyStreet.com.au and get a $20 "member-get-member" bonus (if they used the referral details provided). I'll get $20 each time someone opens an account this way - I'll let you all know if anything turns up in my bank account. Anyhow, I'd gotten $20 bonus when my mom opened an account, so I know it could work (in theory).
Meanwhile I rationlise it as a brisk one hour walk which was good for my health, and provided some cheap entertainment (otherwise I'd have gone to the mall, bought some junk food and browsed the bookshops).
