I'm also a coupon clipper, mainly applicable to items I use regularly anyways (mostly toiletries). I'm not very good at timing sales, so if something non-perishable on my list is on sale, I buy 1-2 extras.
I've been making a more concerted effort to stave off impulse purchases. The rule is that I have to walk away (literally out of the store), even sleep on it, to decide if it's something I really really want and will use. Especially since this year is going to be a big spending year (dance, home improvements). This also allows me the chance to comparision shop online if applicable. In the interest of halting the clutter and money outgo, I've just generally been trying to be more mindful about acquisitions.
Coffee - Maxwell House instant coffee and flavored creamer. Judge away.
I've been brown-bagging lunch for years (the first year I switched over from eating at the cafeteria, I saved $1000 - not just an estimate, I have a spreadsheet). In general, I try to bring my own food when practical and possible instead of having to buy it from a restaurant/shop (e.g. events, travelling).
Borderline cheapskate moves:
* I usually carry my own mints, but if there are mints at the dance studio or someone offers, I will partake of those instead.
* If I am treating myself to a non-brown-bag lunch at work, I try to remember to bring my own can of soda (one of my vices), otherwise purchase from the vending machine, both of which are cheaper than what the restaurant charges.
Btw, hope things look up for your spouse on the job front.
