It's a given, buying in bulk will save you more cash, right?
So, should you skip the grocery store?
Let's talk about the results!
At Costco, spinach will cost you 14 cents per ounce. Kroger's more than doubles that price at nearly 37 cents per ounce.
A rotisserie chicken will cost you almost 22 cents per ounce at Kroger. You save half at Costco; it's about ten cents per ounce.
Kroger is cheaper for salsa, but not by much. It's a difference of a penny per ounce.
You'll save at Kroger (Fry's) buying boneless skinless chicken breast. At Kroger, the price is $1.88 per pound compared to $2.79 per pound at Costco.
In the end, Costco wins with prices up to 63 percent cheaper on 43 of the 50 items compared. Though, you do have to consider the $60 membership fee that Costco requires. View the rest of the comparisons, here .
I wouldn't avoid grocery stores entirely, but buy bulk when you can.
