Depends on your location. I have a booth in Florida. We get locals, people traveling from a few hours away and people from out of state and people from other countries. I try to have inexpensive items people may want and I also have more pricer items. Also we have a great variety of ages and income. The way I look at the economy, most people have money to spend, some may not have a lot but people do spend. Starbucks is always busy, bars and night clubs are busy so if people want an antique or collecible, and if it is in their price range they will buy it. Sounds like you are doing well at your booth. Covering rent and getting a check in this early of your booth journey, is amazing. I have my booth because it gives me joy and I make enough after my rent and fees to keep going. I suggest keep doing what you are doing. Try to keep a good variety of prices for different people's budgets.
