The Real Price Difference

I've spent way too much time price-checking the same items across both sites, and here's the honest breakdown: Walmart wins on groceries almost every time. Not by a little, either. A 32-oz bottle of Heinz ketchup runs around $4.48 at Walmart vs $5.99 or more on Amazon (and that's if you're not buying a third-party listing that charges $8 for "convenience"). Canned goods, paper towels, laundry detergent -- Walmart is consistently 15-30% cheaper on the stuff you buy every week.

Electronics are a different story. Amazon runs deeper discounts during sales events, and if you know how to catch a lightning deal or use a price tracker, you can beat Walmart's everyday price pretty easily. But if you're just clicking in without waiting for a deal? Walmart's "Rollback" pricing on TVs and laptops is legitimately competitive. A 55-inch TCL TV I looked at last fall was $279 at Walmart vs $319 on Amazon outside of Prime Day.

Walmart+ vs Amazon Prime

Amazon Prime is $139/year. Walmart+ is $98/year. That $41 difference matters, but the real question is what you actually use.

Prime gets you: free 2-day shipping on most items, Prime Video (actually good), Prime Music, Prime Reading, early access to deals, and free same-day delivery in most metros. It's a solid bundle if you use the streaming stuff.

Walmart+ gets you: free delivery from Walmart stores (groceries included), free shipping on Walmart.com, 10 cents/gallon off at Exxon/Mobil stations, and Paramount+ included. If you drive and buy groceries regularly, the gas discount alone can offset most of the membership cost. Fill up a 15-gallon tank twice a week and you're saving around $15/month.

My take: if you buy groceries online and drive a gas-powered car, Walmart+ pays for itself fast. If you're a heavy Amazon buyer who watches Prime Video, Prime makes more sense. A lot of households honestly benefit from having both.

Third-Party Sellers -- Where You Have to Be Careful

This is where both platforms get messy. Amazon Marketplace has way more third-party sellers than Walmart Marketplace, which means more price variation, more counterfeits, and more chances to get burned. When I buy anything expensive on Amazon, I filter for "Ships from and sold by Amazon.com" to avoid headaches.

Walmart Marketplace is smaller but growing. The vetting is slightly stricter, and returns through Walmart.com are generally easier -- you can take most items back to a physical store. Amazon returns are usually painless too via UPS dropoff, but you can't just walk it into a store.

Grocery Delivery -- Actual Price Comparison

Here's a quick snapshot I pulled from a real cart:

• Tide PODS 42-count: Walmart $13.97 vs Amazon $16.99
• Bounty Select-a-Size 12 rolls: Walmart $19.97 vs Amazon $21.99
• Hellmann's Mayo 30oz: Walmart $5.48 vs Amazon $6.89
• Folgers Classic Roast 30.5oz: Walmart $9.97 vs Amazon $11.49

That's $10+ more for the same cart on Amazon. Over a month of groceries, that difference adds up to real money.

Bottom line: use Walmart for groceries and everyday household goods. Use Amazon for electronics, specialty items, and anything where Prime's faster shipping actually matters to you. Don't be loyal to either one.
