Seriously, they list coups they find, and put them for us all to see and enjoy. Last week they posted a coupon for Ulta - it was $5 off a $10 purchase. Well I like mascara from there (almost as much as the pricey clinique stuff, but I don't buy it cause it's still $10 a pop- I've started just using the grocery store stuff that's about $4 a tube) and I know sometimes it's on sale buy one get one free. Sure enough, it was, so I used the coupon I found on FCF and got 2 mascaras for $5! Instead of $20. At $2.50 each, they were even way cheaper than the cheap grocery store stuff! Woohoo!
So go check the blog out, check out the list of retail coupons before you go shopping, or find a new recipe!
