I just thought I would give you guys this heads up: You can get a baby carrier (sling) from Seven Slings for the price of shipping (about $12) with the promo code: holidays.
I bought one a couple of months ago with a similar offer and then proceded to carry my 2 year old across Zion's National Park with it. So, I'm a fan. If you are looking for one, this a great chance to get a good deal.
And they didn't even give me anything to tell you this. I just think it's totally worth it!
