Shoppers who finally got used to calmer grocery bills are in for an unwelcome surprise at the dairy case.
Egg prices have jumped again in recent weeks, with the average cost of a dozen Grade A large eggs climbing past $4 in many parts of the country, according to the latest federal retail data.
In some cities, cartons that sat near $2.50 last summer are now pushing $5 or more.
The spike isn't random, and it isn't mainly about inflation overall.
When the virus shows up at a commercial laying facility, the entire flock has to be culled to stop the spread.
That wipes out millions of hens in a single outbreak, and those birds take months to replace.
Fewer hens laying means fewer eggs on shelves, and prices respond fast.
Egg demand peaks in late fall and winter, when baking season collides with holiday cooking.
Retailers also stock up ahead of winter storms, and any hint of a supply crunch sends buyers scrambling.
Add higher costs for feed, fuel, and labor, and you get a carton that costs noticeably more than it did a year ago.
Warehouse clubs and discount grocers often hold prices down longer because they buy in bulk and negotiate contracts ahead of time.
Traditional supermarkets and smaller corner stores tend to pass increases along faster.
That's why two shoppers in the same town can report wildly different prices for the same dozen.
First, stop treating eggs as a fixed weekly purchase.
If your usual store is charging $5.49, check a second store before you buy.
The gap between the cheapest and priciest carton in one neighborhood can easily be $2 or more.
Second, watch the unit price, not the sticker.
A dozen large eggs at $4.99 is 42 cents per egg.
An 18-count at $6.49 is 36 cents per egg.
Buying the larger pack often wins, but only if you'll use them before they go bad.
Eggs keep for three to five weeks in the fridge, so a bigger carton is usually safe if you cook regularly.
Third, lean on substitutes when prices spike.
Baking recipes generally tolerate flax or chia "eggs" fine.
Breakfast burritos, pancakes, and fried rice work with fewer eggs than the recipe calls for.
And if you're a heavy egg eater, now is a reasonable time to rotate in oatmeal, yogurt, or beans for a few meals a week.
Hoarding cartons when headlines get scary is exactly what pushes prices higher in the short term.
Buy your normal amount, shop the sales, and let the market settle.
The good news is that egg prices historically fall back once outbreaks fade and flocks are rebuilt.
The bad news is that rebuilding takes time, and another outbreak can reset the clock.
Expect volatility rather than a straight line back to cheap cartons.
Our take: eggs are still one of the cheapest sources of protein in the store, even at $5 a dozen.
The smart move isn't to swear them off—it's to stop paying full price out of habit.
Check one more store, buy the bigger pack when it makes sense, and keep a couple of backup breakfast options in the pantry.

Your grocery budget will barely notice the swing.
