Endless.com is running a special where you get $5 off if you ship overnight.

If you haven't heard of them (which I hadn't until a few days ago), they sell shoes and handbags. And, their regular policies are great:
1) Free return shipping (wonderful for shoes since you definitely don't want to get stuck with uncomfortable shoes)
2) 110% price guarantee: if you find the same item online for less within 2 weeks, they refund your money plus 10% (I think that's the rule anyhow)

Check them out if you haven't seen them yet. I was impressed.

I love endless. Ever since I found out about them, I have been buying shoes left and right. You have to love the overnight shipping and $5 off promotion. Buy one pair of shoes each time--you will get the promotion off each time. AND they come in a small box when you order individually, so most shoes will fit in the mailbox (to avoid a trip to the post office) if you need to return them.

The best part is their return policy. We all know about the 365 day return policy but they are really quick. If I need to return something, I drop it in the mailbox and I get a refund about a week later. It takes a couple of days to get to them but once they get your return they process it right away (unlike some websites that take forever).

I like endless, but I love to price match at Zappos because Zappos has better customer service and their shipping is sooooooo fast.
