Harris Teeter is having double coupon week at their store. I am planning on at least 2 shopping trips on separate days (because you can take advantage of the doubles only once a day). Check out the Harris Teeter link on the right column for all the stuff you could get free.
When you print coupons from websites, you sometimes have to install a coupon printer. Downloading the printer hasn't bothered my computer at all. Coupons (dot) com is the one I most frequently print coupons from. Other sites you have to put your information down.
If you have a problem with giving websites your email address, you can make a completely different email address up, and use that one each time you sign up for newsletters/special offers, etc. You can forward that email address to your regular one, and put it under a different label and check whenever you'd like (I LOVE gmail!!). That way your regular inbox isn't filled up with a bunch of offers.
