So currently my local Lowe's has 2 of these units in stock in Arid Camo and I was just there and on the app it says there is only 1 available why?

Inventory shown in the app can sometimes lag behind what’s physically in store, as it updates based on recent sales, returns, and system sync timing. It’s possible one unit was recently sold or still being processed, which can cause a temporary mismatch between the app and in-store count. For the most accurate availability, it’s always best to check directly with the store.
