Quite frankly, I don't care for either chain. I have generally found that both are more expensive than smaller, regional or local stores, not to mention the on line avenue. I can't see how a merger would be good for anyone in a crowded and mature market that is moving away from "brick and mortar" stores. Macy's, Sears, Walmart, come to mind. Whether the merger happens, or not, the future does not look bright for either brand, IMO - worse if the merger happens. Niche players and the internet will continue to chip away at their sales and profits.
For years the Cabella's board was divided over physical stores verses catalog and on line sales. That was before on line sales of merchandise became the behemoth it is today. I think the jury is still out over the long term heath of either firm.
