i don't know about your community, but mine has GREAT consignment shops. in fact i've found two new ones in the past couple of months. i am particularly drawn to the ones that have great window displays. of course they are putting great stuff out there to draw you in, but then of course you know that they have great stuff!
i like consignment stores over the online stuff for two reasons. the first is i am a tactile person, i like to see the clothes, touch the shoes, try on the purse, swing the skirts, flaunt the scarves, etc. and because i usually "run into" things that i would have never thought to search for on ebay. or maybe that's why i shouldn't shop them. er.
lastly, a good quality consignment shop will offer a donation service as well. when i drop clothes at my local c.s. - whatever isn't sell-able or is out of season will get donated, in my name, to a local women's shelter or women's clothing mission and i get the tax benefits for it.
life the good life and spread it around. it'll make you feel good.
