The team sold 15 t-shirts totaling $270 in sales and earning a profit through a farmers' market t-shirt sales campaign. Key customers included market enthusiasts, county employees, and vendors. Challenges included a backing out partner, unclear bulk order size, price issues, and slow response times. Lessons learned were to establish per-shirt pricing upfront, follow up clearly with customers, ask definitive questions, and obtain all details from the vendor for clarity.
