Lands End overstocks. Go to their home page and look to the right at the top. I live in Canada and they often have free shipping; but even when they don't, the buys are amazing. For dd: beautiful winter cords for $6 and matching sherpa-lined fleece hoodie for $8. Long-sleeved tye-dyed shirt for $4. Winter wool skirt with shorts underneath for $4. And a fastastic sports bra for me for $2.
Also check their "on the counter" feature. The clothes are mostly not $2 and $3, (though some are), but the quality is incredible and they are all completely guaranteed. Last year, I did have to return a pair of winter boots for dd. She had worn them a couple of months and they sprang a leak. I didn't think they held up reasonably, so I returned them. No problem. I wouldn't abuse the warranty, but it's nice to know I won't have to fight with sales staff and waste my money on something that didn't last.
Oh, just a note: Their sizes run really big. Dd is normally a 7/8 now at places like TCP, but she is barely a 6 in most things at Lands End. That means shopping for their "little kid" line.
I check it all the time and don't really bother with stores anymore. I know it's not as eco-friendly as thrift stores, but the things I buy from them are cheaper than the Salvation Army, unless it's their half-price day. I do still go there, but it's nice to have a brand-new wardrobe for all of us for so little. I've even started buying dh's work clothes on-line from them. At first he was skeptical, until I produced beautiful grey pants that came with free hemming that fit him perfectly for $16.
