I came here all the time while I was freelancing and in charge of my own schedule. It has a lot of points going for it that other thrift shops consistently mess up.
1. It's well lit. You can SEE the clothing, see whatever might be wrong with it, and make an honest assessment. You're never surprised when you leave at the state of the items you've just bought.
2. It is surprisingly clean. Nothing seems to smell, so I can only imagine they've laundered everything thoroughly.
3. There are good quality brands--Ann Taylor, Kenneth Cole, etc. It's mainly items along these lines. You're more likely to find twinsets than clubbing tops here, which if you're over the age of 21 is a good thing.
4. Markdowns and fresh merchandise. These people *know* how to turn over their stock. Because the place is never empty, and there are specials every day, the stock flips rapidly. The merchandise is never the same week to week, so as I mentioned before, it's addictive. You never know what you'll find.
A summary of a few things I've bought here: a 6 dollar designer knit dress, a few silk twinsets ($2-$5), countless heels, two pairs of Birkenstocks and two pairs of Doc Martens ($4-$8), a dressmaker's bust ($5), a pressure cooker ($7)....
You get the picture. The prices aren't rock bottom, but close enough, and the quality of the clothing will help anyone but the stingiest person get over the 50 cents extra.
Can't recommend it enough!
