The most non-sale ever is going on for one day only (September 1st, 2009) at the Lippmann Collection website. If you wanted any of the new releases, including the Celebrate collex, and enjoy the thrill of the luck of the draw, purchase something on this website: one of ten customers will be given a $50 gift certificate. Those are pretty good odds.
You know what else is pretty good? Quite a few of the older Lippmanns for sale for $12 each (+$5 flat shipping) at Hello Gorgeous. A wider selection is available at BeautyBridge (don't forget to sign up for the newsletter for 5% off first orders) for $16 with free shipping on any order. Additionally, BeautyBridge also has a price-matching program: if both Hello Gorgeous and BeautyBridge have the same polish, buy it from BeautyBridge for the free shipping and then email them with the link to Hello Gorgeous within five days of purchase and get the difference refunded.
Also, BeautySak sells a wide selection of Lippmann (including Celebrate collex, Marquee Moon and Don't Tell Mama) for $15 each, free shipping for $50+. And finally, if you're buying a whole huge lot of Lippmann (like, a veritable ton), Nordstrom's has them for the normal price ($16), $5 shipping for orders $50+ (with code: BEAUTY), but you can also get 3% cashback if you have an ebates account.
Ahh, comparison shopping. Always fun. :)
