‘It said it was out of stock online’: Shopper catches Walmart lying about viral $100 vanity

Gone are the days of stepping into a store and not knowing if the item you want will be there. As tracking technology improves (for better and for worse), it's now possible at many stores to track a store's inventory live.

Many retail apps can even accurately pinpoint what aisle an item will be in.

But as far as technology has come, it may not always work out in your best interest.
