My auction friend who opened a store in November, 2012 just folded his hand a few weeks ago. Rent, lack of business and disputes with a partner on what to stock, etc did him in.
Partnerships never work in this business.
In my town, I'm not allowed to put a sign by the road, permanent or temporary. Old ordinance. So I've really got things working against me. But craigslist and Facebook have been my saving grace. Also, my website is 1st page, 1st or 2nd listing, on Google for "thrift store" and "thrift shop" in my area. Also, my Google maps ranking is either A, B, or C when people search that way. That has been a HUGE help in the last 2 weeks. It helps with the smalls, then I just have to work on the bigger items on CL or FB.
Also helps that I just need to make $35 a day to break even. I'm open 6 days. Sundays we go to the flea market, and that's how I make my auction money back.
