Liquor. We drink a lot of alcohol, especially wine. Not super expensive--our staple is trader joes stuff, about 1/2 $3 chuck (which we do enjoy) 1/2 stuff in the $8-10 range (which we also enjoy, sometimes more than the $3 stuff, sometimes less). We also do about 2 crates a year of stuff in the $10-20 range. We drink more expensive scotch ($60-80 range), but more sparingly.
Used to be a bottle of wine with dinner ~3 days a week, a glass of cheaper scotch (i.e., JW red) as a nightcap, and a drink or two throughout the day on Saturdays/Sundays (e.g., irish coffee). We've cut down--mostly because I need to lose weight and this is an easy target--but this is one of our pleasures in life.
Eating out. Spent $400/month on restaurants last year, lots of that being lunches at work. Cutting back on that--I've packed lunch every day this year so far for days that lunch isn't covered by work/I'm not traveling. Aim is a cap of $200/month on restaurants. Managed to get it in for $100 in Jan. Will be higher for Feb (spouse birthday). Fortunately, spouse enjoys cooking (I'm terrible at it and don't have time during the week).
Phone bill. We both have iPhones. I am required to have one for work (only options are Blackberry or iPhone) and my data gets paid for, but I'm not going to ask spouse to have some a cricket phone while I'm using an iPhone. This ends up being $150 a month for both of us, with about half of that being spouse's piece that we could probably cut back.
Coffee/tea. Spouse is a tea fanatic, I am a coffee fanatic. No access to Sam's Club etc for bulk coffee beans, so I end up paying about $10 a bag (I do not go to coffee shops though). I go through.. a lot.. of coffee. Spouse goes through a lot of tea and does not buy cheap stuff (not buying super expensive either, though it's a pretty easy gift for most situations).
I don't have too too much guilt about this stuff because we spent about $48k last year all-in (including our $1,350 of monthly rent and a $6k vacation) on income over $200k, so we're doing ok with saving. But not as well as we could if we went to extremes.
