  • Price: $16.99

Costco’s Kirkland Signature chicken breast is a pantry staple that makes quick meals incredibly easy.

Mix it into chicken salad for sandwiches, toss it into cold pasta salad or use it for quick quesadillas when the grandkids come over. The six-pack also lasts a long time in the pantry.

Costco shoppers regularly praise the product for being made with real chunks of white meat instead of the mushier canned chicken some grocery stores sell.

At roughly $17 for six large cans, it is also an easy way to keep a reliable protein source on hand without breaking your budget and paying deli prices every week.

  • Price: $21.99

Kirkland Signature medium roast coffee has built a loyal following among Costco shoppers for being smooth and reasonably priced compared with many national brands. The large bag is ideal when you have more visitors and life begins to move faster during the summer months.

  • Price: $13.99

Rao’s marinara sauce is one of those Costco staples people buy once and then refuse to replace with another ordinary pasta sauce. It tastes closer to homemade than most jarred sauces and makes quick summer dinners ridiculously easy.

Keep a couple of jars in the pantry for pasta nights, meatball sandwiches or last-minute dinners when family stops by.

  • Price: $14.99

There is a big difference between real maple syrup and the fake pancake syrup most people grew up with. Kirkland Signature organic pure maple syrup has developed a loyal following because it tastes like the real thing without the gourmet price.

This is the type of grocery staple retirees may use more during summer when grandchildren stay over and pancakes become part of the routine again. And considering some grocery stores might charge nearly the same price for bottles half this size, the Costco version is an easy win.

  • Price: $4.53

Cases of bottled water disappear quickly during the summer. People grab them for road trips, cookouts, sports days and visits with the grandkids.

That is why retirees should stock up on Costco’s 40-count Kirkland water cases ahead of summer. At about $4.53 per case, the price per bottle stays far lower than buying drinks at gas stations, convenience stores or vending machines.

  • Price: $14.52

Costco’s Kirkland sparkling water variety pack is an easy win for retirees trying to cut back on soda or sugary drinks. 

The lime, lemon and grapefruit flavors are light enough for everyday drinking, especially during hot afternoons or backyard gatherings. And at roughly $0.41 per can, it is far cheaper than grabbing sparkling water individually at convenience stores or coffee shops.
