We hit the motherload!
Yes. Somewhere around four times per year Express has an End of Season, mass exodus of merchandise. These are my favorite times of the year.
These sales typically begin at 30%, then grow exponentially. If you hold off for about a week, the sales inevitably head up to 70% off. If you wait longer than that, you risk meager pickings (and what's left is left for a reason).
Take advantage of these and get yourself some nice styles in a Kool-Aid's variety of colors.
