Ahh, Costco. The big box store where you can stock up on savings – or spend an entire paycheck in one visit. While the store has deals and steals, it’s important to go with a mind towards savings (and a shopping list!) if you want to shop on a budget. 

GOBankingRates spoke to shopping experts and consulted the internet to find the absolute best deals when it comes to buying groceries at Costco. 

Here are things you can buy at Costco to make the most of your $100.

Rotisserie Chicken

Price: $4.99

This chicken is the quintessential Costco deal. Bhavin Swadas, a savings and shopping expert at Roar The Deal, said: “Not only is it cheap, but it really can be used in many meals throughout this week–on salads or in sandwiches.”

You can use it in lots of different meals, which makes it perfect if you’re trying to save money.

Organic Spinach

Price: $7.45 (price might vary)

Swadas suggests buying the big bag of organic spinach and using it all week long. You can use it in smoothies, salads, and other meals. He adds that it lasts a while in the fridge, so you don’t have to go shopping as often.
