We have both been really good lately about taking our lunches to work. It's kind of a pain sometimes, but it really saves us a lot of money.
We got a rebate check back, for a rebate on Jim Beam and some flavored vodkas, which makes the purchase nearly free.
The books I sold on Amazon netted me $24. It's not a lot, but it takes relatively little work to get the books out the door. One important part of this, though, is that I still have a lot of bubble mailers, which I purchased in bulk back when I was selling books all the time. If I had to buy bubble mailers in small quantities for this, it wouldn't be worth it.
I listed a few of the things I recovered from the attic on Craigslist, but haven't had a lot of interest. Also, I found $5 in a piece of luggage.
I started using Bing Rewards. If you click on that, it will take you to a page to sign up, and if you sign up and start earning points, I'll get some points. I haven't yet decided if it's going to be worth the time involved. You get points for doing well searches through Bing (you can speed it up by using this Bing Rewards Bot). My plan to trade my Bing points for American Airlines AAdvantage points, but like I said, I'm still on the fence about whether it's worth my time.
Not so frugal things:
I got my hair colored, had my eyebrows waxed, and bought Moroccan Oil, which is amazing, but expensive, even with though my hairdresser sells it to me with her discount.
I ordered a metal french press for our upcoming trip. Every time we go camping, coffee is difficult, and this will make it so much better, but still - money spent is money spent.
