I've ordered from fleece footwear before with no issues whatsoever.
I just make sure I know exactly what I want since I think returns could be a pain (as with most online retailers) You would have to pay shipping to get the item back to them, and they do reserve the right to charge a $10 restocking fee.
As for price match at Nordstrom; it seems to be very hit or miss, depending on the rep you get. Of course for Ugg's it has to be an authorized retailer, the price has to be verifiable online, the style, size, color you need has to be in stock, and the tough one... if a code is involved it has to be public, ie: posted on the company website for everyone to see and use.
It seems many folks have been able to get them to waive one or more of the above requirements though. And this is all for the .com division, I've never tried to get Nordstrom to price match in store. I didn't even realize they did that.
