May brings spring celebrations, barbecues, and longer grocery lists, but not all price hikes are justified. Certain products suddenly spike without any real cause, catching shoppers off guard.
While demand might rise, these inflated prices often feel more like a strategic markup than a seasonal necessity. These are the grocery items quietly climbing in price this month, and why that trend has shoppers raising their eyebrows.
Bottled Water Packs

WANT TO SAVE THIS RECIPE?
Despite a steady supply, bottled water prices often rise in May due to an anticipated surge in outdoor events and weekend trips. Stores bank on increased demand from hikers, campers, and beachgoers to charge a premium. With no supply shortage, itโs a seasonal markup that hits wallets hard.
Precut Fruit Bowls
These convenient snack options often see a May price bump, not because of fruit scarcity, but due to packaging and prep inflation. Grocery stores know shoppers want easy grab-and-go options during warmer months. Itโs a convenience tax cleverly disguised as a summer perk.
Grill-Ready Meats
From pre-marinated skewers to burger patties, grilling season prompts a price jump across the meat section. The sudden price rise isnโt always about cost, itโs about timing. Retailers expect youโll pay more for the sake of holiday cookouts and donโt hesitate to raise the stakes.
Packaged Salad Kits
As cookouts and potlucks ramp up, stores boost prices on salad kits, knowing youโll want something quick and green to share. The actual ingredients havenโt gotten pricier, but the packaging and seasonal demand give retailers an excuse to mark them up.
Ice Cream Tubs
Just as the temperatures rise, so do the prices of your favorite ice cream brands. Mayโs warmer days make ice cream a go-to treat, and stores respond with higher price tags. Itโs not about scarcity, itโs about knowing youโll buy it anyway.
Charcoal and Lighter Fluid
Barbecue season triggers inflated pricing on grilling essentials like charcoal and lighter fluid. These items often double in cost around holidays, not due to shortages but planned retail timing. Itโs a classic case of supply meeting forced demand.

Corn on the Cob
Even before peak harvest, corn prices rise in May because stores know shoppers associate it with Memorial Day meals. The increase is often preemptive, based more on expectation than supply. Youโre paying more simply because itโs tradition.
