Okay...le'ts get something straight...I am not cool. For a used clothing store that claims to take used clothing they stink! While bringing some clothes to sell recently, I was met by a hipster who pleasantly gave me a form to fill out which stated, in not so many words, that they only take "hip clothes" and the picking was at the discretion of the clerk. Out of 10 items, he picked one. Paid pretty well (about $12), but felt like a tool as I walked out with my below par clothing (some items originally cost me $50+) under my arm.
The clothes: Smelly as if shoved in a washing machine with a ton of cleanser. Hipster stuff to the roof...if your a female. Men's selection is very small, and unless you want pants that cut off the circulation in your....you know, you will find it hard to spend that well earned credit. Also jeans cost between $12 (fine) and $50 (not fine).
The staff: Cooler than me. Last time I was in, they stupidly giggled behind my back while alternating CD's over the speakers over and over. I also think they have a face piercing minimum (you see, you need to be cool to work there). They are presumptuous and could give a crap if you buy or not.
With REAL used clothing stores like Goodwill that sell the EXACT SAME CLOTHES for a tenth of the price, shopping at Avalon will do nothing for you except make you feel bad about what you wear and what you should be wearing.
