The honest answer to "which is cheaper" depends entirely on what you're shopping for. Here's the breakdown across 6 major categories.
For raw electronics pricing across mainstream SKUs, Walmart wins about 58% of the time — usually by 5-10% on phones, AirPods, and base TVs. But this number is misleading because Best Buy's price match guarantee neutralizes most of the gap. Walk in with a Walmart.com listing showing $50 less and Best Buy will match it on the spot.
The places Best Buy wins outright are the categories Walmart can't or won't serve: open-box electronics (10-25% off new with full warranty, no Walmart equivalent), GPUs at MSRP (Walmart rarely gets allocations from NVIDIA or AMD), gaming laptops (Razer, Alienware, ROG selection is dramatically deeper at Best Buy), and major sale events (Super Bowl TV deals and Black Friday consistently beat Walmart's matching promotions).
Our recommendation: for new electronics at MSRP, check Walmart first. If you find a lower price there, take it to Best Buy and request a price match. For open-box, GPUs, gaming gear, or anything during a Best Buy sale event, skip Walmart entirely.
The Best Buy price match changes the whole game. If you track an item at both retailers, you don't actually have to choose where to buy — you find whichever has the lower price, screenshot the listing, and walk into Best Buy. They'll match it. The savings come from being the one with the data.
PriceWatch tracks identical SKUs at Best Buy, Walmart, and 3 other retailers, then emails you the moment any one drops below your target. You always know which is cheapest — and you have the evidence to request a match.
