Matt,
We have 3 Walmarts here, they all still sell firearms, they have no knowledge of any cut back in firearms sales other than those that already took place in stores that had poor firearm sales. In fact, one of the stores was just built and it too sells firearms! I checked the closest store last weekend, they are doing away with the layaway program, but it will have no effect on special ordering firearms, 50% is still required down on the purchase just as it always has been. If the ordering clerk is knowledgeable, they will check inventory at their supplier, Sports South, before they process the order, those clerks that are somewhat ignorant of the process, don't always check inventory and can lead to long waits. I've only bought one firearm from them, they said it would be 7-10 days before it came in, it arrived in 7.
Hope this helps,
Tim
