Shop it to Me is a free (and fun!) site that sends you email updates on sales happening that include your favorite brands- you choose sizes/colors and prices your interested in. They only include stores you choose and you can opt to receive and email every day or only once a week! They also include awesome discount/free shipping codes as well!
Here's how this deal gets sweeter- for every 10 friends you invite (by email or Facebook) you will receive a $10 gift card to the store of your choice (Whole Foods, Nordstroms, Gap, Old Navy, iTunes, Banana Republic, Macy's, Jamba Juice, Starbucks, Sephora, Bloomingdales or Urban Outfitters). It sound's too good to be true, but it really works! I've received three giftcards in the last few weeks (I choose Whole Foods and it helps with groceries!) just by introducing my friends to the site!
