2026-10-16 → 2026-11-12How this is measured
Each bar is one sync, oldest on the left. Bars show direction only, never amount, and all are the same height for that reason: we record whether a price changed, not what it was. A move under 1% counts as held. We do not keep price history, by design. See our pricing data for the method.

Same product, different quantities. Cost per ounce is the only number that makes them comparable.
The 202.8 ounce is the cheapest per ounce at 8.94¢, 42% less than the 50.7 ounce at 15.5¢.
