I love using coupons. I never thought I would, because of that horrible stereotype that I believed for the longest time:
"Coupons are always for junk food and stuff no one actually buys, especially not healthy/eco-friendly people"
What a lie! Sure, it takes a bit of digging, and maybe you won't get the same amount of savings that you see on Extreme Couponing (then again, those people are a little bit... ridiculous. More on that later if anyone's interested). But every bit counts when you have to stretch your budget just a little bit farther.
For example, Maple Leaf and Schneider's (both Canadian based countries, correct me if I'm wrong) have a "Naturals" line. This includes deli meat with NO NITRITES and no other nasty preservatives. This is obviously not as good as going to the butcher and getting them to put your deli meats in a reusable container, but not all butchers (especially not in grocery stores) will do that for you anyways. Not to mention, there's no ingredients list on those deli meats... I have found save 1$ coupons on both brands of Naturals products, which I have put to good use.
There are also often cereal box coupons, this past summer there was one for a free bunch of bananas up to 2 pounds. Saved me over 2$ for bananas. There have also been some distributed for strawberries and other fresh foods. For me, I don't always buy cereal boxes, but there have been friends and family of mine that give me theirs. Works great for me, and for them.
The same concept goes for paper products. I have found coupons for save 1$ on Cascades Enviro line, which is the Cascades brand line of post consumer recycled products including paper towels and toilet paper. It's even soft like regular Cascades, so no loss there!
Depending on what your regular products are, it is almost always possible to find coupons for them, and save yourself a little bit of cash. Honestly, if all you do is look, it really doesn't cost you anything anyways!
Anyways, that's my spiel. I use some products that have coupons, and some that don't. I prefer to buy things on sale anyways, and if I have a coupon for that product, all the better! But I don't cry if there's none in my stash for it. I might be a little dejected if I've seen coupons for that product but don't have any... but that's just me!
