Here's a helpful post from ShoeBlog.com listing a number of sales and offers from various retailers anxious for you to start your online holiday shopping.
If you set up accounts on websites of your favorite stores (which they usually ask you to do at checkout) you'll get emails about sales and promotions (free shipping, give-aways with purchase, etc.). And if you're registering to win Lucky Breaks sweepstakes, check the box allowing promotional emails. They don't take up much space in your inbox and they can save you some cash! Oh how I love online retailing.
