Historical Price Trends
Olive oil prices at Costco have fluctuated with global harvests and tariffs since 2023. A worldwide shortage drove 2L bottles from under $17 to $24.99 by early 2025, but the 2024/2025 bumper crop reversed this, dropping organic lines significantly.
- January 2023: 3L EVOO steady at $14.99, pre-shortage baseline.
- Mid-2024: Refined packs hit $54 amid shortages; Reddit users noted jumps from $30.
- Summer 2025: Organic 2L falls $24.99 to $18.39; 3L to $27.99 despite 15% EU tariffs.
- October 2025: Refined 2/3L averages $56.99, with sales at $37.99 in Ohio.
- May 2026: Stability holds, with 89% warehouses low/out of stock on refined.
