I have used OPI nail polish in the past and loved it, but was unable to find it in the regular stores.  I recently found it in Kroger for $5/bottle.  I was so excited.

This nail polish goes on smooth and stays on longer than the leading store brands and is worth the little extra cash.

 I've also noticed that the bottle lasts longer and doesn't dry out and get as "clumpy" as some of the brands manufactured by the leading cosmetic companies.
