Ah you're right- I just looked up the premium outlets in north LV. I will have to go there next time I'm in Vegas!
I always get a DY piece at this location when I visit every year - prices are usually 30 to 50 percent off for discountinued pieces. The Saw Grass Mills location in Florida has great selection as well - lots of spiritual bead bracelets, pendants etc. and I bought a citrine cigar ring for 50% off - reg. $1100 got it for $550.
Definately worth a trip next time you are in Vegas...
