but they're often low because they're selling bottom barrel quality goods (like electronics with cheap capacitors that fail quickly or clothes with lower quality fabrics & sewing that don't last). Even products that look the same as other stores will commonly have a Walmart specific SKU that uses cheaper components.
Sadly, this is what customers want. When given the option of a 30$ belt that lasts for life or a 5$ belt that lasts one year, many will go for the latter, and this is who Walmart caters to.
