I've tried it. It's okay. IMO nothing to rave about. It didn't do much for my skin. One jar will last you "forever" tho.
If you count size versus price its pretty much the same as most high-end mositurizer, maybe even cheaper. Cause it's $76 for 3.4 oz, where as most high-end moisturizer are $40-$50 ish but it's only for about 1.5 oz.
If you really want to try it I suggest getting it from Beauty.com. There's a code for $10 off $60 floating on the web soemwhere. And it's no tax (for most states) and free shipping (over $50).
You might be able to get samples from a free-standing Sephora store. I don't believe the Sephora's in JC Penny carry the line.
