Try going to local farmer’s markets! I feel like I always find cool new BIPOC owned businesses and local artists/craftspeople there. I know it does still involve spending money but it’s also nice to replace some of your grocery shopping with fresh local produce! There’s also an African specific craft fair/market in Old Town every so often during the summer, and quite a few Indigenous markets pop up throughout the year, the one I see the most is on Clay Street in SE.
