High diesel prices are pushing up the cost of nearly everything, which is bad news for shoppers and anyone watching inflation.

• Diesel is running over $8 a gallon in California, mostly because of state taxes.
• Nationwide, diesel sits above $6 — far higher than regular gas.
• Diesel moves almost all goods, from Amazon packages to boxes of strawberries.
• When trucking costs rise, those costs land in store prices for everyone.

Outlook: As long as diesel stays this expensive, prices on everyday goods will keep climbing.
