Your price is higher than other retailers or significantly above the same item sold elsewhere. Walmart unpublished or hid the listing under its competitive pricing rules.
Walmart enforces two pricing rules. The Price Parity Rule unpublishes items priced higher on Walmart than on any other site. The Price Leadership Rule hides items priced unreasonably above the prevailing market price. Both rules monitor competitor prices in near real-time, including Amazon, Target, and the seller's own DTC site.
