Buying Coupons?

I never thought I'd be one to do it, but today I officially bought my first coupons online.  Here's the deal, and why I caved.  I was referred to this site by my friend, Wendy, who swears by it, and I was pleasantly surprised.  The coupons were $.05 each, including shipping, and I could pick and choose the ones I needed, and the quantity.  They even ship out same day or next day on Sundays.  This is cheaper than buying an extra paper!  I will be able to get lots of free stuff at the Kroger sale now (Kroger doubles up to and including 50 cents everyday).  So here's the site: www.manufacturerscoupons.net.  You can check it out for yourself, and let me know what you think.  I know I am a huge fan.
