I'm not sure if they have TKMaxx in the US but they have some great stuff. I'm not sure if they sell Uggs there, but there's this brand called Bearpaw that do Ugg-type boots that I personally think are better looking but go for the same sort of price as Uggs, if not more expensive. But you can get Bearpaw in TKMaxx for £40 ($65?) . It's really good value :)
I just bought one last month.
