Dunno about you all but the clear one is always sold out of my Walgreens and I find it indispensable for frankening. I've tried other clear polishes but this one is the smoothest and cheapest, even though they do come in slightly smaller bottles. (Don't let the tall shape fool you as it fooled me for awhile there; I apparently never totally got the whole Piagetan "conservation of liquid" principle and I felt ridiculously dumb when I realized I had been duped.)
Anyway, 99¢ shipping for all beauty products with code SHIP99 (expires: October 1st, 2009).
