Not necessarily. What are they going to do, leave 2 or 3 aisles empty? Not gonna happen, even if it were only gonna last a few weeks or a month. The local Sportsmans and Cabelas both did the same thing.
Retail space is expensive and empty aisles are a bad visual for any retailer of any product. Hell most of them go through and rearrange the entire store every year or two just to break up the traffic patterns and direct more traffic past the impulse purchase items.
Rearranging a couple of aisles is small potatoes. They did it overnight and they can undo it overnight just as easily.
I don't see that as meaning anything about anything other than what isn't available right now.
