i agree with you on the food front, DF and I spend a bit compared to some people on here in terms of fruit and veges and groceries. we buy mostly organic and locally grown produce, the organic part makes it more costly, but the locally grown part makes it a bit cheaper!
i admit, i skimp on work clothes for my second job. i buy mens polo shirts for $6, and throw them out after about a year.
but clothes in general, is a bit of a mix and match. i buy what i like and what feels good on and flattering, so sometimes it might be a $5 tee or a $50 tee. i don't overspend though.
i go cheap on casual shoes, it's the one thing i hardly ever spend large amounts on. i wear them nearly every day, and they get trashed. i have in the past had good quality ones, and they get trashed the same amount as cheap ones
i buy lots of pairs of flats (usually the ballet style flats) for around $10-$15 a pair, and they last me abuot 6 months each pair.
hmmm. oh and kitchen stuff! like plates, bowls, cups etc all come from op-shops. not just because they are cheap though, also because i love the older styles.
