I get coupons from a variety of places. Here are as many as I can think of off the top of my head...
Newspaper Inserts. Our dollar store (conveniently located right next to my workplace) sells the Sunday paper for $1. Most Sundays, I'll stop over on one of my breaks and pick up a copy. I also like to check the "used papers" basket at Caribou Coffee, because people leave their papers and coupons behind sometimes. Every now and then someone will leave a paper behind at the hotel, but not often.
Online. Unless they specifically state otherwise (and I usually try anyways), you can print online coupons twice from each computer you have available to you. A lot of them require you to install their coupon printer program, which is fine to do.
- Coupons.com is a good source.
- Smartsource.com is also good.
- Redplum.com has a few coupons, and every now and then they have some good ones.
- Target offers their own printable coupons, which you can stack with manufacturer coupons to get better deals. I've heard Walmart is starting to offer printable coupons too, but I haven't tried them yet.
- Specific company websites. Think of a product, and go find their website. Chances are, they have a coupon available.
- Facebook. As with the company website, think of a product and go find it on Facebook and/or Twitter. Some have good deals or freebies. I am not on Twitter, but I've heard they have some there as well.
- E-mail newsletters. Just like going to the company website will probably get you coupons, so will signing up for their newsletter. Some of my favorite ones are Betty Crocker, Pillsbury, and Barnes & Noble.
Word of Mouth Programs. These are some of my favorites, because you get free stuff.
- Kraft First Taste. They give their members access to coupons for free products that are just coming out. You can then fill out a survey about how you liked the product. The more you participate, the better your odds of getting the next offer (at least, from what I've found).
- Vocalpoint. They send random mailings of high value coupons and occasional full size products.
- SheSpeaks. I just joined this one tonight, so I'm not sure how it is, but the description says they send out products to try for free, with multiple coupons.
Magazines. I have subscriptions to A LOT of magazines (probably between 15 and 20). All were free except for 2 of them - Real Simple was $5 for 1 year on Amazon awhile back, and All You was $16 for 2 years awhile back too. Most magazines offer at least a couple coupons, and All You is jam packed with them.
Free samples. Samples are fun in and of themselves, but they usually come with coupons.
The mail. Not only do I get my sample coupons, but I get random others in the mail sometimes. Some are from places I've gone (and signed up for, like our local restaurants). Others are just delivered sporadically to everyone, or as part of a regional marketing promotion (like that $5 Walmart gift card I got last month).
Entering codes. I do My Coke Rewards, Huggies Enjoy the Ride Rewards, Pampers Gifts to Grow, Disney Movie Rewards, and I just signed up for Tropicana Juicy Rewards. I would also suggest RecycleBank if it's available in your area.
Contacting companies. Last fall, I tried a Scrubbing Bubbles bathroom cleaner. I was really impressed with it, so I sent the company an e-mail through their website. They thanked me for my comments and sent me 2 free product coupons. That won't necessarily always be the result, but if you really like something, why not?
Through blogging. I have only gotten a few this way, but some companies are looking for bloggers to review products, and will send you the product/coupons for free products to try in return for your public opinions. I don't know too much about this one, but I saw an offer for it once, and figured I'd try it out.
