This is especially true in their health and beauty aids sections which are actually above average prices. So don't think that because it's Walmart that they always have better prices - many times not, and that's what they want you to think.
Comparison shop for the items you need. Smaller stores have less hassle at checkout and often friendlier people who care about you as a customer. Walmart is just a machine designed for efficiency, but they also make a lot of mistakes at checkout so make sure to check your receipts carefully. I found several mistakes not in my favor, like charged for someone else's items.
Be smart - shop at other places than Walmart. Don't assume they have the cheapest prices - they want you to think that, and don't.
Reason of review: Pricing issue.
