I've tried to do the coupon cutting thing many times. Usually, I forget I have a coupon in my wallet when I pay. It seemed a stupid waste of time to me. Lately, I've tried it again. With great success.
I shop at Old Navy and GAP on Tuesday, when it's 20% off for using your card. Add that to a 10% off coupon for completing their purchase survey and that is a nice savings. If your coupon code is for Old Navy, you can still get 5% off if you use it at GAP and vice versa.
Before making an online purchase, I search for coupons for that store. For example by typing in "Kohl's online coupon" the coupon codes from RetailMeNot saved me almost $50 on what would have been a $117 purchase. $15 = no shipping charge and 30% off my purchase. Sweet!
I've been going to CVS for the first time in my life. I signed up for a CVS Saver Card for greater discounts. Like, milk for $1.99! I even check the sales each week online.
And, I've learned Walgreen's has great sale prices. The other day, I saved over $17 with coupons on Mini Me's school supplies. I went online to print manufacturer's coupons then used coupons from the Walgreen's flyer to maximize savings.
What I refuse to do, is purchase items I would not normally purchase, simply because I have a coupon or it is on sale. I think, ultimately, this saves me money.
