When do Aldi's summer savings start?

Aldi's price cuts began June 5 and will be valid through Labor Day.

The price cuts will likely save shoppers about $100 million – similar to the amount of money shoppers collectively saved with reductions last year and more than the $60 million shoppers saved in 2023. What are some products at Aldi that will be less expensive?

Clancy’s: Chili Lime Potato Chips - was $1.89, is now $1.79. 
Friendly Farms: 2% Ultra-Filtered Milk – was $4.39, is now $3.89.
Millville: Protein Pancake Mix – was $3.79, is now $3.49. 
Mama Cozzi’s: Mini Pizza Bagels – was $6.29, is now $5.99. 
Summit: Popz Prebiotic Soda - was $1.59, is now $1.49.
