As Costco adjusts prices for 2026, retirees on fixed incomes should act strategically. Several staple items have seen significant price increases over the past year, and experts expect more adjustments in January. Stock up now on these essentials before prices climb higher, according to recent price tracking data. 
Kirkland Signature Organic Extra Virgin Olive Oil
- Price: $20.99 (expected to increase soon)
Smart retirees should grab this organic extra virgin olive oil at Costco before prices rise further. Olive oil has seen dramatic increases recently — a two-pack of 3-liter bottles jumped from $25 in 2021 to over $50 by 2023, according to Food Republic. The 2-liter organic version currently offers better value, but with ongoing supply challenges in Spain and other producing regions, expect continued price pressure throughout 2026.

Kirkland Signature Salted Butter
- Price: Check in-store (recently increased)
Butter prices hit $3 per pound in late 2024, up 15% from 2023, as reported by The Takeout, using U.S. Department of Agriculture (USDA) forecasts. Costco shoppers reported the Kirkland Signature salted butter jumping nearly $1 in a single week during early 2025. With cattle numbers declining and milk production down, retirees should stock their freezers now — butter freezes beautifully for up to six months, making bulk buying practical.

Kirkland Signature Fully-Cooked Bacon
- Price: $18 (up from $11.49)
This convenient pre-cooked bacon has seen a 58% price increase over recent years, according to Food Republic. Raw bacon hit $6.70 per pound nationally in January 2025, making even Costco’s fully cooked version expensive. For retirees who struggle with cooking, this microwaveable option remains worthwhile despite the increase — just buy it now before another reset.

Kirkland Signature Panko Breaded Shrimp
- Price: $22.80 (up from $17.99)
Despite the increase, these frozen shrimp at Costco still offers good value for the 2.5-pound package, according to Cruising Costco. For retirees avoiding cooking complexity, these pre-breaded shrimp bake easily and provide quality protein. With seafood prices generally rising, current pricing may look reasonable by mid-2026.

Snack Factory Organic Pretzel Crisps
- Price: $8.99 (up from $6.89)
These popular 28-ounce pack of pretzel crisps at Costco saw an increase of over $2 since 2020, according to Tasting Table. While not exclusive to retirees, the lighter, crunchier texture appeals to seniors with dental concerns. The organic certification and portion control make them worthwhile at current prices before further adjustments.
Bonus: Smart Shopping Strategy
Buy non-perishables in bulk now, freeze items like butter and bacon, and monitor your local warehouse for additional price changes. Executive members earning 2% back on purchases can offset some increases. Most importantly, stock pantries and freezers during January before spring price adjustments take effect.
