Did you know that Nordstrom runs designer days? Even with the designer's less expensive stuff? Neither did I. A week or two ago, I noticed that the Michael Kors $98 studded leather fingerless gloves on my Wish List were marked down 25%. (I check my Wish List at least daily for markdowns.) I thought I'd better pounce to get my size rather than wait and show the list to DH for Christmas. Much to my surprise, the price bounced right back to the regular price, but thankfully after I'd ordered. I went to a bricks'n'mortar Nordstrom to exchange one pair because the left size was cut smaller for some reason, and the SA explained to me about the one day sale. And because this was Nordstrom, I was able to get the exchanged pair for the sale price.
Note: I suppose if I had a relationship with a SA and consistently bought a certain line, the SA would alert me to such specials.
