We don't sleep on Nordstrom Rack as a secret-weapon shopping destination. In addition to its steady inventory of premium brands with super-slashed price tags, the site throws more deals into the mix with surprise flash sales — and the biggest one just dropped.

And unless another retailer starts giving goods away for free, this event takes the long-weekend sale cake.
