For years, 6 oz. cans of tuna were $.65 - .79. Now 5 oz. cans cost around $.80 to $1.00.
15 oz. cans of Salmon around $1.30 for years, now around $2.89.
Quarts of mayonnaise have risen from around $1.98 to $3.50 for a common brand, and about the same for less and more expensive brands.
Egss have increased greatly also, along with most all grocery store items.
These increases over the past three or four years.
You’re shopping in the wrong place. Try Aldi’s. Tuna is still $.69, mayo $1.95, milk<$3 per gallon, and eggs fluctuate with the season but generally cheaper than anywhere else. You buy from the cardboard cases and bag your own. It’s owned by Trader Joe’s and carries some of the same stuff but still no 2 buck Chuck (3 buck Chuck now).
