One of the beautiful things about online shopping is that there are some phenomenal deals to be had. However, unless you spend a portion of most days checking out your favorite online stores, sometimes it's hard to catch the best deals. And, if you're anything like me, you know there's no reason to pay full price for workout clothes -- if you can afford to be patient, the items you need will always go on sale.

Shop It To Me Running is a fast, easy, and commitment-free way to score great deals on the workout clothes you need. From shoes to sports bras, you can select the brands and sizes you'd like to receive updates on, and when those items go on sale, Shop It To Me Running will email you. You can opt to receive notifications daily, twice weekly, or once a week.

While I'm excited to receive my next update, the thing I'm most thrilled about is how much money I could save on shoes. I was able to enter my exact shoe preference (Mizuno Wave Elixir, Size 8). I know it can be scary to order running shoes without trying them on, but if you have a specific brand and model that you've worn (I'm on my third pair), there's really no risk.

And, if you're not really in the market for tennis shoes or running clothes, you still might want to check out the original Shop It To Me, where you can get deals on all kinds of clothes -- you choose the items, brands, and sizes, and they serve as a personal sale shopper. And it's all free!
