• I compared prices of organic produce, meat, and dairy at Whole Foods and Walmart in the same area.
• Whole Foods has a far bigger selection, with nearly every item listed as organic.
• Walmart doesn't primarily sell organic products, but the ones it had were mostly cheaper than at Whole Foods.

Whole Foods sells mostly organic and natural products, but it's also known for high prices.

Walmart, however, is known for affordable prices with the majority of shelf space dedicated to non-organic products.

I visited both stores in the Buffalo, New York area to see where to get the better deal on organic groceries.

Whole Foods easily has the greater selection, with organic products prominently displayed and organic varieties of just about every item.

Walmart has plenty of produce, but the organic options are much scarcer and all grouped together.

I compared an 18-item basket of organic produce, meat, and dairy at both stores, and found Walmart was about 15% less expensive.

The Walmart basket cost $58.28, while the comparable basket at Whole Foods cost $67.25 for a price difference of $8.97.

Walmart has the lower price on a bunch of organic celery, at $2.36 compared to $2.99 at Whole Foods.

Broccoli, though, is a better deal at Whole Foods at $2.99 per pound, a savings of 67 cents over Walmart.

Organic cauliflower had one of the biggest price disparities.

It was $5.46 for a head of cauliflower at Whole Foods, compared to $3.86 at Walmart.

Green kale was pricier at Walmart at $7.12 per pound, with a difference of nearly $2 per pound.

Walmart won the lower price on carrots at $1.96 per bunch, though Whole Foods wasn't too much pricier at $2.29.

Organic avocados came out to $2.50 at Whole Foods and $1.66 at Walmart.

Yellow onions were priced closely at both stores, at $1.42 per pound at Walmart and $1.66 per pound at Whole Foods.

Organic garlic is a slightly better deal at Whole Foods, with savings of about 20 cents per pound.

Bananas are a bit pricier at Whole Foods, at 79 cents per pound, versus 62 cents per pound at Walmart.

The same patterns in produce held true for meat.

Whole Foods was the more expensive destination for organic ground beef priced at $8.99 per pound, over a dollar more than Walmart's $7.28 price.

Boneless, skinless chicken breasts were $6.68 per pound at Walmart, much less than the $9.99 price at Whole Foods.

A half gallon of store-brand milk was slightly more affordable at Whole Foods, priced at $4.49 for a savings of 35 cents.

Generally, I found that organic items were priced lower at Walmart, with the biggest savings on meat.

The selection is much more limited at Walmart, though.

Despite its reputation, Whole Foods wasn't actually that much more expensive than Walmart, at least if you stick to basic produce and meat and avoid pricier prepared items.

A customer after the absolute lowest prices would probably do better at Walmart, especially if they planned to buy large quantities of organic meat.

A committed consumer of organic foods would probably want to stick to Whole Foods, which has hundreds of organic items that aren't available at Walmart.
