I did it! Earlier this week, I actually purchased coupons online. (I really wanted more of the $2.25 Electrosal coupons!) I have heard of so many people doing this, but I just haven't done it. It was so easy and my coupons came in just a couple of days. I especially loved that I was able to pay with my paypal account.
I got my desired coupons from http://www.thecouponclippers.com/ . If there are specific coupons that you want, I would suggest you check them out.
