"I advise those families with a single income to get most of their supplies from Costco because of the quality they offer and the prices," said Eric Sornoso, co-founder of Mealfan.

Sornoso has a few specific products he believes are excellent choices for money-conscious families. Here are five things you must buy for your family while on a single-income budget.

  • Price: $11.69 for two 28-ounce jars

"This organic peanut butter contains no added sugar or preservatives," explained Sornoso. "It is very nutritious and can be used as a sandwich spread, in smoothies or as a snack besides fruits and vegetables."

For families with growing children, this is the perfect spread to put on any quick meal and toss in your kid's lunch bag, backpack or even a mini-snack in their pocket.

  • Price: $24.99 for 30 rolls of 380 sheets each

Costco's Kirkland Signature bath tissue is highly regarded for its sterility and comfort, making it a basic must-have item in every home, according to Sornoso.

This essential product is something that households -- no matter what budget -- go through quickly. But when you shop Kirkland Signature brand at Costco, you'll notice the savings adding up over time.

"People with big families will embrace the big quantity since that will mean [less] shopping, and you will always have what you need," added Sornoso.

Sornoso said, "Extra virgin olive oil is perhaps the most essential item in everyone's kitchen, and the Kirkland Signature organic extra virgin olive oil is excellent and affordable." He described how this olive oil is ideal for cooking, salad dressings and the like, which makes it a valuable component of a healthy meal while being affordable.

  • Price: $21.99 for six 6-ounce cans

"This canned salmon is very good and healthy for those times when foods are needed urgently," said Sornoso. Not only is fish a good source of Omega-3 fatty acids, but it has a multitude of uses, including as an ingredient in salads, sandwiches and soups as a source of protein.

"The value pack guarantees you have a healthy protein source at your disposal and still save money," Sornoso said.

  • Price: $15.99 for 320 gummy vitamins

Forget the regular daily vitamins for kids. Costco's Kirkland Signature children's complete multivitamin can keep your little ones, and your budget, feeling healthy.

"You can get these gummies at an economical price," Sornoso said. "They are favorites with children for their flavors and with parents for their nutritional and affordable aspects."
