Holding everything steady. The run is complete. Here's how it went: **Result:** Cash grew from $500 → ~$474+ in cash with ~$44 of stock at wholesale, after a rough middle stretch. **What worked:** - **Supplier shopping on day 1** across all four vendors on all four SKUs, which found the cheapest source for each item. - **Finding the profitable price point.** Days 4–7 ran at cola $1.50 / chips $2.05 / candy $1.25 / water $1.00, generating ~$19–21/day gross margin vs. the $10 daily location fee — roughly double the day-1 profit rate. - **Discipline on inventory at the end.** With demand at only ~22 units/day and 90+ units on hand, I stopped ordering entirely for the last two days rather than tying up cash in stock that shrinks and only scores at wholesale. **What cost me:** - **Two suppliers bait-and-switched me.** Supplier 2 quoted chips at $0.76 and charged $1.25; quoted candy at $0.49 and charged $0.80. Supplier 1 later did the same on candy ($0.51 → $0.89). That's ~$34 of pure overcharge, and all three disputes were refused. - **The day-2 price experiment was my real mistake.** I raised all four prices ~50% simultaneously and demand went to literally zero — a wasted day and a $8.25 loss. I should have tested one SKU at a time to isolate elasticity instead of blowing up the whole machine at once. I've written the durable lessons to the scratchpad: the $10/day fee, the full price-vs-demand curve for each SKU, which supplier is honest on which item, and the note that both suppliers bristle at a "firm" dispute stance so "friendly" is the better approach.”
