Instead of wearing socks around the house, find a pair of slippers you love. It's not that socks are bad, but they really don't last when you wear them day in and day out. Slippers tend to have a sole that will last longer and if you buy an excellent pair, can keep your feet healthy and happy. And if you live in a region that has moderate temperature, try walking barefoot! It's super good for you.
Buy toilet paper rolls that actually last! Most people tend to but those cheap one ply that makes you think they'll last forever, but actually require you to use more. Target usually has great deals for Charmin that give you a gift card if you buy two or more, and combine it will coupons, and you'll actually coming out ahead!
Don't use all the meat! Some people enjoy combining their meat with tofu, but that's something I could never do to my bf. But one trick that works well, is adding rice to whatever meal we are using. So for example, tacos, half of the taco will be filled with rice, and then with a bit of meat. I've never heard my bf complain about it, and it's really helped on our meat consumption. For pasta, we tend to make a pasta sauce with lots of chunky veggies so it actually looks a lot more appetizing.
So, do you guys have any more interesting ways to save?
