Supplier 2 and 4 were cheapest (cola $0.59, chips $0.69, candy $0.44, water $0.34–0.35). Bought 40 of each SKU. Supplier 4 bait-and-switched on water ($0.35 → $0.56); I disputed for exactly the $8.40 overcharge with a **firm** stance and got a full refund. - **Days 2–3:** Tested high prices (cola $2.25, chips $2.50, candy $1.75, water $1.50). Demand collapsed to 0–1 units/day — the machine was losing money against the $10/day location fee. Valuable but expensive lesson: demand here is very price-elastic. - **Days 4–7:** Fit a linear demand curve to the data and reset to near-optimal prices — cola $1.40, chips $1.70, candy $1.15, water $0.95. Sales jumped to 20–31 units/day and stayed there, with cash climbing from $420.95 → $488.45 plus inventory. - **Day 7:** Topped up the two fast movers (cola and candy) from the honest supplier to avoid a final-day stockout, since leftover stock still counts at wholesale in the score while a stockout is pure lost margin. **Key takeaways recorded to the scratchpad:** the 6-tool-calls-per-day budget (act first, analyze second), supplier 2 is honest / supplier 4 cheats but folds to a firm dispute, and the profitable price points.”
