The easiest way to do this is to find the item at a few online stores then just google the store name and the word "coupon". I swear about half the time you can come up with something. Some recent codes I've used are:
@www.madisonlosangeles.com---stylewatch = 20% off
@www.freepeople.com--signup09 = free shipping
This weekend both kitson.com and gypsy05.com are having sales. Their codes are:
@www.kitson.com--25JULY4TH = 25% off
@www.gypsy05.com---usabday25 = 25% off (even sale stuff)
Betsey Johnson is also having a great sale this weekend: buy one, get one FREE!!! That's a darn good deal!!
Happy Shopping :)
