I rarely buy big name-brands at the grocery store - almost never, in fact. Store brands are just as good and quite a bit cheaper. I also bring my own cloth bags to the store - I get $.03 off each bag of groceries, but that's not why I do it - I hate plastic, is why!
I go clothes shopping maybe once or twice a year - mostly because I hate shopping for clothes, but also because they're freakin' expensive! I plan to buy most of my stuff second-hand from now on (in 2 weeks I will be a full time student again
Ditto shoes - I wear them until they wear out completely.
I never go to first-run movies anymore - I go to the rep cinemas and pay $6 or $4 to see movies that ran 6 months ago. Suits me just fine.
I haven't bought a book for almost a year - I big-puffy-heart the public library
Ditto CDs - I'm never home, so I hardly ever listen to them anyway.
I cancelled my bus pass subscription ($88 a month
- and that was a savings - w/out the subscription, it's $100!) I bike or walk just about everywhere. I bike at least 10K per day, so I'm in great shape now!
I brownbag my lunch. Not only that, but I wash and re-use the sandwich baggies until they rip (again, more because I hate plastic and hate throwing it out than because of the cost - but you know, I haven't had to buy sandwich bags in over 2 years!). I used to eat out every day, but once I decided to go back to school, that was the end of that!
I bring my own mug to the coffeeshop - $.10 discount
Also it's better for the environment.
I gave up my hair stylist. Now I get my hair cut for half the price at the cheapy place at the University.
My apartment. I live alone. This is very expensive, but I need my own space.
My glass collection. I love cobalt blue glass and Depression glass. Every once in awhile, if I see a piece I really like, I will buy it - because I know if I don't, somebody else will snap it up!
Coffee. I love coffee. Especially espresso I love going out for coffee and sitting in cafes writing in my journal or reading.
Beer and wine - I still buy these for home use, which is quite a bit cheaper than going out, but I love to go out for drinks with friends!
Environmentally friendly dishwashing liquid and laundry detergent - it costs a lot more than the regular stuff, but then again, it lasts a lot longer, so maybe it's more of a frugality in the long run
I just shelled out $50 to have my bike repaired by professionals - almost half the price of the bike itself. But again, it's my only mode of transport, so I guess I should invest in proper care for it!
