Use code MOM2012 to get free shipping with a $15 purchase. They offer many items priced at just $1, so you could potentially get 15 items for $15 with free shipping.
I have ordered several products from this website. Some have been great, and some weren't so great. I generally buy my cosmetics from Walmart, Walgreens, or CVS. Since I'm not already used to something like Clinique or Mary Kay, I find the ELF cosmetics to be comparable to drug store cosmetics.
Here are some of my favorite products:
I love this powder. However, it doesn't last long (only 3-4 weeks), and it's annoying to scrape it out of the edges to finish it off.
This has lasted over 3 weeks on my toes!
Products I wasn't so impressed with:
There are still lots of products that I haven't tried. ELF has codes for free shipping (usually with a minimum purchase of $13-15) every few weeks. Since I'm already used to drugstore quality cosmetics, I enjoy trying some new products. You could also find some good items to give as gifts (teacher appreciation pampering set, thank-you for a friend, etc.).
