I'm about to do the same. For the past few months we've been spending about $100 a week on travel/food for winter sports. Its all over now & I need to put that money away, not find other things to spend it on!
I have so many things I want/need, but its all going to have to wait because I want to take my kids on an amazing holiday at christmas, so I have to do this! Going to grab the one or 2 things I need at the shops is fine. Its just down the road. But then I usually buy an iced coffee, a chocolate or something for the kids. Only about $5, but it adds up! The hot lunch every Friday while food shopping I can do without too. The iced coffee & pop top/s chips I usually get with my fuel...
Maybe I can allow the iced coffee... Its only $3 a few times a week.
