I've had a store for 6 years now only breaking even but i also run 3 other businesses out of the building that are doing good. Mainly work consignment with local storage unit buyers and pickers but also run a pack/ship business and a online auction site and a ebay drop-off. Trouble with a store is overhead - electric, phone, internet, advertising etc etc etc. If your selling stuff you get from unit you need lots of foot traffic unless you got a good client list already built up. I've gone the consignment route because i like to selling part lots more than the buying. About 95% of our sells are online right now as that where i have the most experience.
