I think most of these, if not all, are on my wishlist. If you know a nailphile, it's likely some of these are on their Holiday wishlist, too. Some of these might be a little pricey, depending on where you choose to buy. I can't say that I recommend ebay, unless you've been stalking the prices and know, for sure, that you're getting a good deal.
Most of these polishes are Limited Edition, which, unfortunately, the most coveted polishes usually tend to be. That can mean they're either Hard To Find, (HTF) Expensive, ($$$) or both! But, if any of these polishes are on the wishlist of a polish addict you love... Have no doubt, you'll be their favorite person times a hundred if one of these polishes is under the tree.
And if it's Clarins 230 aka Unicorn Pee*? Well... you'll be their BFF for life!!! And yes, $63.50 is currently the lowest listing for Clarins 230 on ebay. The highest is over $200. Personally, I wouldn't pay over $80 for it, but that's just me.
